Struct ValidationContext 

pub struct ValidationContext { /* private fields */ }

Mutable state threaded through prepare and validate.

Implementations

impl ValidationContext

pub fn new() -> Self

Fresh context for JSON input.

pub fn for_text() -> Self

Context for text input (query strings, forms, path segments).

pub fn with_strict(self, strict: bool) -> Self

Force strict (true) or lax (false) mode for every model, like Pydantic’s model_validate(strict=...).

pub fn at_root(self, item: impl Into<LocationItem>) -> Self

Prefix every reported location with item (e.g. "body").

pub fn with_data<T: Any + Send + Sync>(self, value: T) -> Self

Attach user data readable by validators (Pydantic validation context).

pub fn data<T: Any + Send + Sync>(&self) -> Option<&T>

User data of type T, if attached.

pub fn config(&self) -> &ModelConfig

Settings of the model currently being processed.

pub fn allows_text_coercion(&self) -> bool

Whether lax string → scalar coercion is allowed right now.

pub fn is_strict(&self) -> bool

Effective strictness (override beats model config).

pub fn input_kind(&self) -> InputKind

Input kind.

pub fn with_config<R>( &mut self, config: ModelConfig, f: impl FnOnce(&mut Self) -> R, ) -> R

Run f with config installed, restoring the previous one after.

pub fn at<R>( &mut self, item: impl Into<LocationItem>, f: impl FnOnce(&mut Self) -> R, ) -> R

Run f with item appended to the current location.

pub fn location(&self) -> &[LocationItem]

Current location.

pub fn error( &mut self, code: impl Into<Cow<'static, str>>, message: impl Into<String>, )

Record an error at the current location.

pub fn push(&mut self, error: FieldError)

Record error, prefixing its location with the current location.

pub fn check(&mut self, result: Result<(), FieldError>)

Record the result of a rule check at the current location.

pub fn has_errors(&self) -> bool

Whether any error has been recorded.

pub fn error_count(&self) -> usize

Number of errors recorded so far (useful to detect new ones).

pub fn take_errors(&mut self) -> ValidationError

Take the collected errors, leaving the context empty of errors.

Trait Implementations

impl Debug for ValidationContext

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ValidationContext

fn default() -> ValidationContext

Returns the “default value” for a type.
