Avro schema are constant, spec are designed to be constant. As a result, side effects are acceptable in protocol ToSpec. assert is used more than usual. Wherever an inconsistent state is detected, it's prefered to raise a argsual error message rather than unclear exception or worse: an erroneous output.

Reference: https://avro.apache.org/docs/1.8.2/spec.html. Any difference should be considered a bug.

->avro-fixed? clj

Sequence of 8-bit unsigned bytes. Returns a singleton of the given size.

->avro-logical-decimal? clj

(->avro-logical-decimal? precision scale)

Represents an arbitrary-precision signed decimal number of the form precision × 10-scale. Annotates Avro bytes or fixed types. Represented with a java.math.BigDecimal in generated Java sources.

array-spec-value clj

avro-double? clj

Imprecise. Double precision (64-bit) IEEE 754 floating-point number

avro-float? clj

Imprecise. Single precision (32-bit) IEEE 754 floating-point number

avro-int? clj

Int: 32-bit signed two's complement integer

avro-logical-date? clj

Represents a date within the calendar, with no reference to a particular time zone or time of day. Annotates an Avro int, where the int stores the number of days from the unix epoch, 1 January 1970 (ISO calendar). Represented with org.joda.time.LocalDate in generated Java sources.

avro-logical-duration? clj

This logical type is supported as is with no overloading of its underlying type. It is currently unknown to package org.apache.avro/LogicalTypes so should probably be used with caution. You're alone; good luck.

Represents an amount of time defined by a number of months, days and milliseconds. This is not equivalent to a number of milliseconds, because, depending on the moment in time from which the duration is measured, the number of days in the month and number of milliseconds in a day may differ. Other standard periods such as years, quarters, hours and minutes can be expressed through these basic periods. Annotates Avro fixed type of size 12, which stores three little-endian unsigned integers that represent durations at different granularities of time. The first stores a number in months, the second stores a number in days, and the third stores a number in milliseconds. Represented with custom named type fixed(12) in generated Java sources.

avro-logical-time-micros? clj

Represents a time of day, with no reference to a particular calendar, time zone or date, with a precision of one microsecond. Annotates an Avro long, where the long stores the number of microseconds after midnight, 00:00:00.000000. Represented with primitive long in generated Java sources.

avro-logical-time-millis? clj

Represents a time of day, with no reference to a particular calendar, time zone or date, with a precision of one millisecond. Annotates an Avro int, where the int stores the number of milliseconds after midnight, 00:00:00.000. Represented with org.joda.time.LocalDate in generated Java sources.

avro-logical-timestamp-micros? clj

Represents an instant on the global timeline, independent of a particular time zone or calendar, with a precision of one microsecond. Annotates an Avro long, where the long stores the number of microseconds from the unix epoch, 1 January 1970 00:00:00.000000 UTC. Represented with primitive long generated Java sources.

avro-logical-timestamp-millis? clj

Represents an instant on the global timeline, independent of a particular time zone or calendar, with a precision of one millisecond. Annotates an Avro long, where the long stores the number of milliseconds from the unix epoch, 1 January 1970 00:00:00.000 UTC. Represented with org.joda.time.DateTime in generated Java sources.

avro-long? clj

Long: 64-bit signed integer

convenient-args clj

These args are not meant to be your default choice, but they are somehow convenient to use.

dove-spec-keyword clj

enum-obj-spec-value clj

enum-str-spec-value clj

epoch clj

hierarchy-derive clj

(hierarchy-derive parent descendant)

ignore-spec? clj

(ignore-spec? args)

ignored-specs clj

Spec not to be infered. Useful if you want to use some custom specs. Used by to-spec! to keep track of specs and register a spec only once.

map-spec-value clj

MapQualifier clj protocol

-qualify-map clj

(-qualify-map schema args)

Recursively qualify keys of a map to match some schema namespace.

optional-key? clj

qualify-map clj

(qualify-map value schema explicit-union-types)

Recursively qualify keys of a map to match some schema namespace. Example dumb explicit-union-types:

(fn [possible-types path value]
  (if value
    (last possible-types)
    (first possible-types)))

record-spec-symbol clj

spec-def clj

(spec-def args spec-symbol)

ToSpec clj protocol

to-spec! clj

(to-spec! this args)

Recursively infer and register spec of record-schema and any nested schemas.

transform-keys clj

union-spec-symbol clj

unqualify-map clj

Recursively unqualify keys of a map, provided they're keyword.
