Result extension

Required methods

fn context<K, V>(self, k: K, v: V) -> Result<T> where
    K: Into<Cow<'static, str>>,
    V: Into<Cow<'static, str>>, 

Appends key, value pair to context of the last frame

Arguments

  • k - A key
  • v - A value

fn context_with<F>(self, f: F) -> Result<T> where
    F: FnOnce() -> (String, String), 

Appends key, value pair to context of the last frame

Arguments

  • f - A function which must return tuple (key, value)

fn frame(self) -> Result<T>

Appends new, anonymous, frame

Anonymous means that the frame does not have a name.

fn frame_with<F>(self, f: F) -> Result<T> where
    F: FnOnce() -> String, 

Appends new frame

Arguments

  • f - A function which must return frame name

fn frame_with_name<N>(self, name: N) -> Result<T> where
    N: Into<Cow<'static, str>>, 

Appends new frame

Arguments

  • name - A frame name
