Trait binrw::error::CustomError

pub trait CustomError:
    Display
    + Debug
    + Send
    + Sync
    + Sealed { }

The CustomError trait describes types that are usable as custom errors in a BinResult.

This trait is automatically implemented for any type which implements the same traits as std::error::Error, so anything you would normally use as an error in other code is also a valid CustomError, with the additional restriction that it must also be Send + Sync.

This trait is Sealed.

Implementations

impl dyn CustomError

pub fn downcast<T: CustomError + 'static>( self: Box<Self>, ) -> Result<Box<T>, Box<Self>>

Attempts to downcast a boxed error to a concrete type.

Errors

If the downcast fails, Self will be returned.

pub fn downcast_mut<T: CustomError + 'static>(&mut self) -> Option<&mut T>

Returns some mutable reference to the boxed value if it is of type T, or None if it isn’t.

pub fn downcast_ref<T: CustomError + 'static>(&self) -> Option<&T>

Returns some reference to the boxed value if it is of type T, or None if it isn’t.

pub fn is<T: CustomError + 'static>(&self) -> bool

Returns true if the boxed type is the same as T.
