Struct minijinja::Error

pub struct Error { /* private fields */ }

Represents template errors.

If debug mode is enabled a template error contains additional debug information that can be displayed by formatting an error with the alternative formatting (format!("{:#}", err)).

Example

Here is an example of you might want to render errors:

match template.render(ctx) {
    Ok(result) => println!("{}", result),
    Err(err) => {
        eprintln!("Could not render template:");
        eprintln!("  {:#}", err);
    }
}

Implementations

impl Error

pub fn new<D: Into<Cow<'static, str>>>(kind: ErrorKind, detail: D) -> Error

Creates a new error with kind and detail.

pub fn with_source<E: Error + Send + Sync + 'static>(self, source: E) -> Self

Attaches another error as source to this error.

pub fn kind(&self) -> ErrorKind

Returns the error kind

pub fn name(&self) -> Option<&str>

Returns the filename.

pub fn line(&self) -> Option<usize>

Returns the line.

pub fn debug_info(&self) -> Option<&DebugInfo>

This is supported on crate feature debug only.

Returns the template debug information is available.

The debug info snapshot is only embedded into the error if the debug mode is enabled on the environment (Environment::set_debug).

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl Error for Error

fn custom<T>(msg: T) -> Self where
    T: Display, 

Used when a Serialize implementation encounters any error while serializing a type.

impl From<ErrorKind> for Error

fn from(kind: ErrorKind) -> Self

Performs the conversion.

impl PartialEq<Error> for Error

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
