Type Alias pingora_error::Result

pub type Result<T, E = BError> = Result<T, E>;

Syntax sugar for std::Result<T, BError>

Aliased Type

enum Result<T, E = BError> {
    Ok(T),
    Err(E),
}

Variants

Ok(T)

Contains the success value

Err(E)

Contains the error value

Trait Implementations

impl<T> Context<T> for Result<T, BError>

fn err_context<C: Into<ImmutStr>, F: FnOnce() -> C>( self, context: F ) -> Result<T, BError>

Wrap the Err(E) in Result with more context, the existing E will be the cause.

impl<T, E> OrErr<T, E> for Result<T, E>

fn or_err(self, et: ErrorType, context: &'static str) -> Result<T, BError>

where E: Into<Box<dyn ErrorTrait + Send + Sync>>,

Wrap the E in Result with new ErrorType and context, the existing E will be the cause.

fn or_err_with<C: Into<ImmutStr>, F: FnOnce() -> C>( self, et: ErrorType, context: F ) -> Result<T, BError>

where E: Into<Box<dyn ErrorTrait + Send + Sync>>,

Similar to or_err(), but takes a closure, which is useful for constructing String.

fn explain_err<C: Into<ImmutStr>, F: FnOnce(E) -> C>( self, et: ErrorType, exp: F ) -> Result<T, BError>

Replace the E in Result with a new Error generated from the current error
