Struct mysql::Compression
source · pub struct Compression(_);
Expand description
When compressing data, the compression level can be specified by a value in this enum.
Implementations
sourceimpl Compression
impl Compression
sourcepub const fn new(level: u32) -> 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”.
sourcepub const fn none() -> Compression
pub const fn none() -> Compression
No compression is to be performed, this may actually inflate data slightly when encoding.
sourcepub const fn fast() -> Compression
pub const fn fast() -> Compression
Optimize for the best speed of encoding.
sourcepub const fn best() -> Compression
pub const fn best() -> Compression
Optimize for the size of data being encoded.
