Struct MessageRingBuffer 

pub struct MessageRingBuffer { /* private fields */ }

A ring buffer for messages.

Implementations

impl MessageRingBuffer

pub fn with_capacity(capacity: usize) -> MessageRingBuffer

Create a new instance the ability to hold capacity amount of messages.

pub fn push_overwrite( &mut self, level: MessageLevel, origin: String, message: impl Into<String>, )

Push a message from origin at severity level into the buffer, possibly overwriting the last message added.

pub fn copy_all(&self, out: &mut Vec<Message>)

Copy all messages currently contained in the buffer to out.

pub fn copy_new( &self, out: &mut Vec<Message>, previous: Option<MessageCopyState>, ) -> MessageCopyState

Copy all new messages into out that where received since the last time this method was called provided its previous return value.

Trait Implementations

impl Clone for MessageRingBuffer

fn clone(&self) -> MessageRingBuffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MessageRingBuffer

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for MessageRingBuffer

fn eq(&self, other: &MessageRingBuffer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
