Struct hyper::header::Quality [−] [src]

pub struct Quality(pub u16);

Represents a quality used in quality values.

Can be created with the q function.

Implementation notes

The quality value is defined as a number between 0 and 1 with three decimal places. This means there are 1000 possible values. Since floating point numbers are not exact and the smallest floating point data type (f32) consumes four bytes, hyper uses an u16 value to store the quality internally. For performance reasons you may set quality directly to a value between 0 and 1000 e.g. Quality(532) matches the quality q=0.532.

RFC7231 Section 5.3.1 gives more information on quality values in HTTP header fields.
