Helper on our Results for context addition and modification.

Required Methods

fn context<C>(self, context: C) -> Self

where C: Into<Cow<'static, str>>,

Add human context to the error.

fn context_with<F, C>(self, context_fn: F) -> Self

where F: FnOnce() -> C, C: Into<Cow<'static, str>>,

Add human context to the error via a closure.

fn attach<C>(self, context: C) -> Self

where C: AnyDebugSendSync + 'static,

Add machine context to the error.

This will not override existing attachments. If you want to replace and override any existing attachments of the same type, use attach_override instead.

fn attach_with<F, C>(self, context_fn: F) -> Self

where F: FnOnce() -> C, C: AnyDebugSendSync + 'static,

Add machine context to the error via a closure.

This will not override existing attachments. If you want to replace and override any existing attachments of the same type, use attach_override instead.

fn attach_override<C>(self, context: C) -> Self

where C: AnyDebugSendSync + 'static,

Set machine context in the error.

This will override existing attachments of the same type. If you want to add attachments of the same type, use attach instead.

fn attach_override_with<F, C>(self, context_fn: F) -> Self

where F: FnOnce() -> C, C: AnyDebugSendSync + 'static,

Set machine context in the error via a closure.

This will override existing attachments of the same type. If you want to add attachments of the same type, use attach instead.

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.
