Struct mysql_async :: Compression Copy item path

impl Compression

pub const fn new(level: u32) -> Compression

Creates a new description of the compression level with an explicitly specified integer.

The integer here is typically on a scale of 0-9 where 0 means “no compression” and 9 means “take as long as you’d like”.

pub const fn none() -> Compression

No compression is to be performed, this may actually inflate data slightly when encoding.

pub const fn fast() -> Compression

Optimize for the best speed of encoding.

pub const fn best() -> Compression

Optimize for the size of data being encoded.

pub fn level(&self) -> u32

Returns an integer representing the compression level, typically on a scale of 0-9
