Enum StringComparison 

#[repr(i32)]
pub enum StringComparison {
    CurrentCulture = 0,
    CurrentCultureIgnoreCase = 1,
    InvariantCulture = 2,
    InvariantCultureIgnoreCase = 3,
    Ordinal = 4,
    OrdinalIgnoreCase = 5,
}

Specifies the culture, case, and sort rules to be used by the comparisons of strings.

Variants

CurrentCulture = 0

Compare strings using culture-sensitive sort rules and the current culture.

CurrentCultureIgnoreCase = 1

Compare strings using culture-sensitive sort rules, the current culture, and ignoring the case of the strings being compared.

InvariantCulture = 2

Compare strings using culture-sensitive sort rules and the invariant culture.

InvariantCultureIgnoreCase = 3

Compare strings using culture-sensitive sort rules, the invariant culture, and ignoring the case of the strings being compared.

Ordinal = 4

Compare strings using ordinal (binary) sort rules.

OrdinalIgnoreCase = 5

Compare strings using ordinal (binary) sort rules and ignoring the case of the strings being compared.

Implementations

impl StringComparison

pub fn compare(self, a: &str, b: &str) -> Ordering

Compares two strings (string.Compare(a, b, comparison)).

pub fn equals(self, a: Option<&str>, b: Option<&str>) -> bool

Whether two strings, either of which may be null, are equal (string.Equals(a, b, comparison)).

pub fn starts_with(self, source: &str, prefix: &str) -> bool

Whether source starts with prefix (source.StartsWith(prefix, comparison)).

pub fn index_of(self, source: &str, value: &str) -> i32

The position of the first occurrence of value in source in UTF-16 code units, or -1 (source.IndexOf(value, comparison)).

pub fn contains(self, source: &str, value: &str) -> bool

Whether value occurs in source (source.Contains(value, comparison)).
