Enum TemplateError 

pub enum TemplateError {
    MissingVariable(String),
    InvalidFilter(String),
    ParseError(String),
}

Errors that can occur during template parsing or rendering.

Variants

MissingVariable(String)

A {{variable}} referenced in the template has no value in the context and no default filter was supplied.

InvalidFilter(String)

An unrecognised filter name was used (e.g. {{x | frobnicate}}).

ParseError(String)

The template text could not be parsed (e.g. an unclosed {{).

Trait Implementations

impl Clone for TemplateError

fn clone(&self) -> TemplateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateError

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

Formats the value using the given formatter.

impl Display for TemplateError

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

Formats the value using the given formatter.

impl Error for TemplateError

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 TemplateError

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