Struct liquid_core::Error

pub struct Error { /* fields omitted */ }

Compiler error

Implementations

impl Error

pub fn with_msg<S: Into<KString>>(msg: S) -> Self

Create a new compiler error with the given message

pub fn trace<T>(self, trace: T) -> Self where
    T: Into<KString>, 

Add a new call to the user-visible backtrace

pub fn context<K, V>(self, key: K, value: V) -> Self where
    K: Into<KString>,
    V: Into<KString>, 

Add context to the last traced call.

Example context: Value that parameters from the trace evaluate to.

pub fn cause<E: ErrorClone>(self, cause: E) -> Self

Add an external cause to the error for debugging purposes.

pub fn into_err<T, E>(self) -> Result<T, E> where
    Self: Into<E>, 

Simplify returning early with an error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

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
