Module validate 

Check a JSON value against a generated schema.

The engine is behind this module: nothing outside it sees how a schema is held, only Violations. Generated schemas keep to params::KEYWORDS, the engine checks those keywords alone, and Keyword has a variant for each that can reject a value.

Structs

ParamsCheck

The compiled schema of one action’s with: block.

Pointer

A JSON pointer (RFC 6901), held as its segments.

SchemaError

A schema the engine could not compile, which is a mistake in the generator rather than in a ceremony.

Validator

A compiled schema.

Violation

One way a value fails a schema.

Enums

Anchor

Where a diagnostic about a violation points: at a key, or at a value.

Keyword

A keyword that rejected a value, and what it asked for.

Matched

How many of a oneOf’s alternatives a value matched, when it was not exactly one.

Values

Whether a message may quote the value it is about.

Functions

The check for action, compiled on first use and kept for the process.
