Enum ExprError 

pub enum ExprError {
    Params(ParamError),
    Graph(ExprGraphError),
    Shape(ExprShapeError),
}

Errors produced while constructing or rebuilding expressions.

Variants

Params(ParamError)

A parameter operation failed.

Graph(ExprGraphError)

A serialized graph was structurally invalid.

Shape(ExprShapeError)

An operation received incompatible expression shapes.

Trait Implementations

impl Clone for ExprError

fn clone(&self) -> ExprError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExprError

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

Formats the value using the given formatter.

impl Display for ExprError

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

Formats the value using the given formatter.

impl Error for ExprError

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.
