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

Schema for binary data: a JSON array of byte values (0..=255), or a string once base64(), base64url() or hex() is set. Built with vld::bytes().

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

Schema for any JSON value, with optional shape checks. Built with vld::json_value().

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.

ZTryTransform

Transforms the output with a fallible function: an Err becomes a validation issue (IssueCode::Custom { code: "transform" }, the error’s text as the message).

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 (serialized untagged, like Either).

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.

Schema

A schema with everything the enabled features need (here: VldSchema; with openapi also the JSON Schema traits).

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.
