Trait Checker

pub trait Checker: Sized {
    type W: Write;

    // Required methods
    fn should_update(&self) -> bool;
    fn new_writer(&self) -> Result<Self::W>;

    // Provided methods
    fn buffered(self) -> Buffered<Self, Self::W> { ... }
    fn buffer_with(self, size: usize) -> Buffered<Self, Self::W> { ... }
    fn build(self) -> Result<(Rolling<Self, Self::W>, Token<Self::W>)> { ... }
}

Required Associated Types

type W: Write

Required Methods

fn should_update(&self) -> bool

fn new_writer(&self) -> Result<Self::W>

Provided Methods

fn buffered(self) -> Buffered<Self, Self::W>

create a buffered writer with default size: 4K

fn buffer_with(self, size: usize) -> Buffered<Self, Self::W>

create a buffered writer with specified buffer size

fn build(self) -> Result<(Rolling<Self, Self::W>, Token<Self::W>)>

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.
