Enum SurfaceError 

pub enum SurfaceError {
    NotCaps,
    MissingField(&'static str),
    BadField(&'static str),
}

A reason a SurfaceCaps value could not be parsed from an Expr.

Parsing fails closed: a malformed descriptor never yields partial caps.

Variants

NotCaps

The value was not a surface/caps-tagged map.

MissingField(&'static str)

A required field was missing.

BadField(&'static str)

A field carried the wrong value shape.

Trait Implementations

impl Clone for SurfaceError

fn clone(&self) -> SurfaceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SurfaceError

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

Formats the value using the given formatter.

impl Display for SurfaceError

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

Formats the value using the given formatter.

impl Eq for SurfaceError

impl Error for SurfaceError

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 SurfaceError

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