Struct PreSerializeError 

pub struct PreSerializeError {
    pub kind: PreSerializeErrorKind,
    pub failed_format: Option<&'static str>,
    pub format_stack: Vec<&'static str>,
}

Error returned by Prepare::prepare.

failed_format identifies the innermost named format that attached context. With the alloc feature, format_stack retains the complete format trace.

Fields

kind: PreSerializeErrorKind

The underlying failure category.

failed_format: Option<&'static str>

The innermost named format that reported the failure, if available.

format_stack: Vec<&'static str>

Nested format names collected while propagating the error.

Implementations

impl PreSerializeError

pub exec fn new(kind: PreSerializeErrorKind) -> Self

Creates an error without attached format context.

pub exec fn length_too_large() -> Self

Creates a serialized-length overflow error.

pub exec fn not_compliant(kind: ComplianceErrorKind) -> Self

Creates a value-compliance error.

pub exec fn custom(msg: &'static str) -> Self

Creates a format-specific value-compliance error.

pub exec fn push_format(self, current_format: &'static str) -> Self

Adds a named format to the error’s propagation trace.

pub exec fn failed_format(&self) -> Option<&'static str>

Returns the innermost named format that attached context.

pub exec fn format_trace(&self) -> &[&'static str]

Returns the collected format trace, or an empty slice without alloc.

Trait Implementations

impl Clone for PreSerializeError

exec fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for PreSerializeError

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

Formats the value using the given formatter.

impl Display for PreSerializeError

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

Formats the value using the given formatter.

impl Error for PreSerializeError

Available on crate feature std only.

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 PreSerializeError

fn eq(&self, other: &PreSerializeError) -> 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.
