Struct ValidationError 

#[non_exhaustive]
pub struct ValidationError {
    pub field: String,
    pub message: String,
}

Represents a specific validation error.

field identifies the offending element using a dotted path (channel.title, item.0.link, feed.id, entry.2.updated, …) so downstream tooling can dispatch on the field without parsing strings. message is the full human-readable error text and is what std::fmt::Display writes — preserving the bare-string format that previous releases of this crate emitted as the RssError::ValidationErrors payload.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

field: String

The dotted path identifying the field that failed validation.

message: String

The full human-readable error text. Read via Display / to_string(); matches the string format used in pre-v0.0.6 releases.

Implementations

impl ValidationError

pub fn new<F: Into<String>, M: Into<String>>(field: F, message: M) -> Self

Constructs a ValidationError.

field should be the dotted path (e.g. "channel.title"); message is the full human-readable error text and is what std::fmt::Display writes back out — keeping the bare-string format used by earlier releases of this crate.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl Eq for ValidationError

impl Error for ValidationError

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.

impl PartialEq for ValidationError

fn eq(&self, other: &ValidationError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
