[−][src]Struct actix_web::http::header::Quality
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 1001 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.
