Struct androidy_log::Writer

pub struct Writer { /* fields omitted */ }

Android log writer.

By default every write is buffer unless buffer overflow happens. Buffered input is flushed on Drop or via manual call.

Implementations

impl Writer

pub const fn new_default(prio: LogPriority) -> Self

Creates new instance using default tag Rust

• prio - Logging priority.

pub fn new(tag: &str, prio: LogPriority) -> Self

Creates new instance using:

• tag - Log message tag, truncated to first 23 characters.
• prio - Logging priority

pub const unsafe fn from_raw_parts(
    tag: MaybeUninit<[u8; 24]>,
    prio: LogPriority
) -> Self

Creates new instance with:

• tag - Log message’s tag as raw C string, that must be ending with 0. It is UB to pass anything else.
• prio - Logging priority

pub fn buffer(&self) -> &[u8]

Returns content of written buffer.

pub fn flush(&mut self)

Flushes internal buffer, if any data is available.

Namely it dumps stored data in buffer via __android_log_write. And resets buffered length to 0.

pub fn write_data(&mut self, data: &[u8])

Writes supplied text to the buffer.

On buffer overflow, data is logged via __android_log_write and buffer is filled with the rest of data

Trait Implementations

impl Drop for Writer

fn drop(&mut self)

Executes the destructor for this type.

impl Write for Writer

fn write_str(&mut self, text: &str) -> Result

Writes a string slice into this writer, returning whether the write succeeded.

fn write_char(&mut self, c: char) -> Result<(), Error>

Writes a char into this writer, returning whether the write succeeded.

fn write_fmt(&mut self, args: Arguments<'_>) -> Result<(), Error>

Glue for usage of the write! macro with implementors of this trait.
