coercerclj/s

(coercer schema coercion-matcher)

Inputs: [schema coercion-matcher :- CoercionMatcher]

Produce a function that simultaneously coerces and validates a datum. Returns a coerced value, or a schema.utils.ErrorContainer describing the error.

coercer!clj/s

(coercer! schema coercion-matcher)

Inputs: [schema coercion-matcher :- CoercionMatcher]

Like coercer, but is guaranteed to return a value that satisfies schema (or throw).

Like `coercer`, but is guaranteed to return a value that satisfies schema (or throw).

CoercionMatcherclj/s

A function from schema to coercion function, or nil if no special coercion is needed. The returned function is applied to the corresponding data before validation (or walking/ coercion of its sub-schemas, if applicable)

(first-matcher matchers)

Inputs: [matchers :- [CoercionMatcher]] Returns: CoercionMatcher

A matcher that takes the first match from matchers.

json-coercion-matcherclj/s

(json-coercion-matcher schema)

A matcher that coerces keywords and keyword eq/enums from strings, and longs and doubles from numbers on the JVM (without losing precision)

safeclj/s

(safe f)

Take a single-arg function f, and return a single-arg function that acts as identity if f throws an exception, and like f otherwise. Useful because coercers are not explicitly guarded for exceptions, and failing to coerce will generally produce a more useful error in this case.

string->booleanclj/s

(string->boolean s)

returns true for strings that are equal, ignoring case, to the string 'true' (following java.lang.Boolean/parseBoolean semantics)

string->uuidclj/s

Returns instance of UUID if input is a string. Note: in CLJS, this does not guarantee a specific UUID string representation, similar to #uuid reader
