Struct noodles_sam::record::MappingQuality [−][src]
pub struct MappingQuality(_);
Expand description
A SAM record mapping quality.
Mapping quality ranges from 0 to 254 (inclusive), where higher is better.
The value 255 is reserved as a marker for a missing mapping quality.
Methods from Deref<Target = Option<u8>>
🔬 This is a nightly-only experimental API. (option_result_contains
)
option_result_contains
)Returns true
if the option is a Some
value containing the given value.
Examples
#![feature(option_result_contains)]
let x: Option<u32> = Some(2);
assert_eq!(x.contains(&2), true);
let x: Option<u32> = Some(3);
assert_eq!(x.contains(&2), false);
let x: Option<u32> = None;
assert_eq!(x.contains(&2), false);
Converts from &Option<T>
to Option<&T>
.
Examples
Converts an Option<String>
into an Option<usize>
, preserving
the original. The map
method takes the self
argument by value, consuming the original,
so this technique uses as_ref
to first take an Option
to a reference
to the value inside the original.
let text: Option<String> = Some("Hello, world!".to_string());
// First, cast `Option<String>` to `Option<&String>` with `as_ref`,
// then consume *that* with `map`, leaving `text` on the stack.
let text_length: Option<usize> = text.as_ref().map(|s| s.len());
println!("still can print text: {:?}", text);
Converts from Option<T>
(or &Option<T>
) to Option<&T::Target>
.
Leaves the original Option in-place, creating a new one with a reference
to the original one, additionally coercing the contents via Deref
.
Examples
let x: Option<String> = Some("hey".to_owned());
assert_eq!(x.as_deref(), Some("hey"));
let x: Option<String> = None;
assert_eq!(x.as_deref(), None);
