Implementations

impl MetadataValue

pub fn matches_eq(&self, other: &MetadataValue) -> bool

Check if this value matches another for equality

pub fn compare(&self, other: &MetadataValue) -> Option<Ordering>

Compare for ordering (returns None for incompatible types)

pub fn contains_str(&self, needle: &str) -> bool

Check if this string value contains a substring

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

Check if this string value starts with a prefix

pub fn ends_with(&self, suffix: &str) -> bool

Check if this string value ends with a suffix

Trait Implementations

impl Clone for MetadataValue

fn clone(&self) -> MetadataValue

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MetadataValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for MetadataValue

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for MetadataValue

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<bool> for MetadataValue

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f32> for MetadataValue

fn from(f: f32) -> Self

Converts to this type from the input type.

impl From<f64> for MetadataValue

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i32> for MetadataValue

fn from(i: i32) -> Self

Converts to this type from the input type.

impl From<i64> for MetadataValue

fn from(i: i64) -> Self

Converts to this type from the input type.

impl PartialEq for MetadataValue

fn eq(&self, other: &MetadataValue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
