Enum TemplateError 

#[non_exhaustive]
pub enum TemplateError {
    UnclosedPlaceholder(String),
    UnmatchedClosingBrace(String),
    EmptyPlaceholder,
    UnknownPlaceholder(String),
    Render(String),
    MissingVariable(String),
}

Errors returned by template parsing and rendering.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnclosedPlaceholder(String)

The template has an unclosed placeholder (missing closing brace).

UnmatchedClosingBrace(String)

The template has an unmatched closing brace.

EmptyPlaceholder

A placeholder inside the template has an empty name.

UnknownPlaceholder(String)

A placeholder inside the template is not recognized.

Render(String)

A custom error returned by the renderer callback.

MissingVariable(String)

A dynamic variable required by the template had no value.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TemplateError

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

Equality operator ==.

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

Inequality operator !=.
