Struct bflog::ContextWriter

pub struct ContextWriter<'a> { /* private fields */ }

Temporary structure that can write additional context to a log entry.

Implementations

impl<'a> ContextWriter<'a>

pub fn pretty(&mut self) -> &mut Self

Sets the context writer to “pretty” mode, which outputs each context item on a separate line with pretty formatting.

pub fn with<V: Serialize>(&mut self, key: &str, value: &V) -> &mut Self

Adds a context item with a given key and value to the log entry.

This method is identical to write but is better named when the method is repeatedly chained from a logger method.

pub fn write<V: Serialize>(&mut self, key: &str, value: &V) -> &mut Self

Writes a context item with a given key and value to the log entry.

This method is identical to with but is better named when the writer is stored in a variable and used procedurally.

pub fn finish(self)

Completes the log entry.

This method does nothing, but serves as an easy way to drop a writer stored in a variable without the need for a block.

Trait Implementations

impl<'a> Drop for ContextWriter<'a>

fn drop(&mut self)

Executes the destructor for this type.
