Structs

FieldResult

Result of validating a single field.

IssueBuilder

Fluent builder for constructing a single ValidationIssue.

ParseResult

Result of lenient parsing: contains the (possibly partial) struct and per-field diagnostics.

ValidationIssue

A single validation issue with path, message and received value.

VldError

Collection of validation errors.

ZAny

Schema that accepts any JSON value. Created via vld::any().

ZArray

Schema for array validation. Created via vld::array().

ZBoolean

Schema for boolean validation. Created via vld::boolean().

ZBytes

ZCatch

Wraps a schema with a fallback value returned on ANY validation error.

ZChar

Schema for a single char: a JSON string of exactly one Unicode scalar value. Created via vld::char().

ZCustom

Schema from a custom validation function.

ZDefault

Wraps a schema to provide a default value when the input is null or missing.

ZDescribe

Wraps a schema with a human-readable description.

ZDiscriminatedUnion

Discriminated union: chooses a schema based on a discriminator field value.

ZDuration

Schema for std::time::Duration. Created via vld::duration().

ZEnum

Schema for string enum validation. Created via vld::enumeration().

ZEnumOf

Schema mapping fixed strings to values of T. Created via vld::enum_of().

ZF32

Schema for f32 numbers. Created via vld::f32().

ZFromSerde

Schema that deserializes the JSON value into any T: DeserializeOwned. Created via vld::from_serde().

ZFromStr

Schema that parses a JSON string with T: FromStr. Created via vld::from_str().

ZInteger

Schema for a sized integer (i8..u64, isize, usize). Created via vld::i8() … vld::u64(); ZInt (vld::number().int()) is ZInteger<i64>.

ZIntersection

Intersection of two schemas: input must satisfy both.

ZJsonValue

ZLazy

Lazy schema for recursive/self-referencing data structures.

ZLiteral

Schema for exact value matching. Created via vld::literal().

ZMap

Schema for validating a JSON array of [key, value] pairs into a HashMap.

ZMessage

Override the error message for an inner schema.

ZNever

Schema that rejects every value (invalid_type, expected never). Created via vld::never().

ZNull

Schema that accepts only null. Created via vld::null().

ZNullable

Wraps a schema to allow null.

ZNullish

Wraps a schema to make it both optional and nullable (nullish).

ZNumber

Schema for number validation (f64). Created via vld::number().

ZObject

Dynamic object schema with runtime-defined fields.

ZOptional

Wraps a schema to make it optional.

ZPath

Schema for filesystem paths. Created via vld::path() (read its security note: confine untrusted paths with within).

ZPipe

Chains two schemas: output of the first is serialized to JSON, then parsed by the second.

ZPreprocess

Applies a preprocessing function to the JSON value before validation.

ZRecord

Schema for validating JSON objects as key-value records. Created via vld::record() (HashMap<String, V>) or vld::record_with_keys() (HashMap<K, V>); ordered() switches the output to a BTreeMap.

ZRefine

Adds a custom refinement check to a schema without changing its output type.

ZSet

Schema for validating a JSON array into a HashSet (unique elements).

ZSocketAddr

Schema for socket addresses (ipv4:port / [ipv6]:port; hostnames are rejected). Created via vld::socket_addr().

ZString

Schema for string validation. Created via vld::string().

ZSuperRefine

Refinement that can produce multiple errors at once.

ZTransform

Transforms the output of a schema after successful parsing.

ZUnion2

Union of two schemas. Tries the first, then the second.

ZUnion3

Union of three schemas.

Enums

Either

A value that can be one of two types.

Either3

A value that can be one of three types.

IssueCode

Validation issue code — describes what went wrong.

PathSegment

A segment in a validation error path.

Traits

IntoLiteral

Trait for types that can be used as literal values.

VldInput

Trait for types that can be used as input to schema parsing.

VldParse

Trait for types that can be parsed from a serde_json::Value.

VldSchema

Core validation schema trait.

Functions

flatten_error

Flatten a VldError into a simple field-based structure.

prettify_error

Format a VldError into a human-readable string.

treeify_error

Convert a VldError into a tree structure that mirrors the schema.

Type Aliases

ZInt

Integer schema with i64 output. Created via vld::number().int().

ZOrderedRecord

Record with BTreeMap output (sorted keys); see ZRecord::ordered.
