Struct VldError 

pub struct VldError {
    pub issues: Vec<ValidationIssue>,
}

Collection of validation errors.

Errors are accumulated (not short-circuited), so all issues are reported at once.

Fields

issues: Vec<ValidationIssue>

Implementations

impl VldError

pub fn new() -> VldError

Create an empty error container.

pub fn single(code: IssueCode, message: impl Into<String>) -> VldError

Create an error with a single issue (no received value).

pub fn single_with_value( code: IssueCode, message: impl Into<String>, received: &Value, ) -> VldError

Create an error with a single issue and the received value.

pub fn with_prefix(self, segment: PathSegment) -> VldError

Prepend a path segment to all issues (used for nested objects/arrays).

pub fn merge(self, other: VldError) -> VldError

Merge another error’s issues into this one.

pub fn is_empty(&self) -> bool

Check if there are no issues.

pub fn push(&mut self, code: IssueCode, message: impl Into<String>)

Push a single issue (no received value).

pub fn push_with_value( &mut self, code: IssueCode, message: impl Into<String>, received: &Value, )

Push a single issue with the received value.

impl VldError

pub fn issue(&mut self, code: IssueCode) -> IssueBuilder<'_>

Start building a new issue with the fluent API.

Call .message(...), .path_field(...), .received(...) etc., then .finish() to push the issue.

Example

use vld::prelude::*;

let mut errors = VldError::new();
errors
    .issue(IssueCode::Custom { code: "my_check".into() })
    .message("something went wrong")
    .path_field("field_name")
    .finish();

Trait Implementations

impl Clone for VldError

fn clone(&self) -> VldError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VldError

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

Formats the value using the given formatter.

impl Default for VldError

fn default() -> VldError

Returns the “default value” for a type.

impl Display for VldError

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

Formats the value using the given formatter.

impl Error for VldError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
