Trait SiftError

pub trait SiftError<T, C>
where
    C: Display + Send + Sync + 'static,
{
    // Required methods
    fn context(self, ctx: C) -> Result<T>;
    fn with_context<F>(self, op: F) -> Result<T>
       where F: Fn() -> C;
    fn help(self, txt: C) -> Result<T>;
}

Trait that defines the behavior of errors that Sift manages.

Required Methods

fn context(self, ctx: C) -> Result<T>

Adds context that is printed with the error.

fn with_context<F>(self, op: F) -> Result<T>

where F: Fn() -> C,

Like context but takes in a closure.

fn help(self, txt: C) -> Result<T>

User-help text.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<T, C> SiftError<T, C> for Result<T>
