Trait Split

pub trait Split:
    Send
    + Sync
    + 'static {
    // Required methods
    fn split_once<'s>(&self, haystack: &'s str) -> Option<(&'s str, &'s str)>;
    fn split<'s>(&self, haystack: &'s str) -> impl Iterator<Item = &'s str>;
}

Pattern usable for splitting strings. Used in Delimited and DelimitedEntries deserializers.

Standard implementations

• &str: matches a string exactly
• [char; _]: matches any of the chars
• LazyRegex: matches a regular expression

Required Methods

fn split_once<'s>(&self, haystack: &'s str) -> Option<(&'s str, &'s str)>

Splits the given haystack at most once from its start. This generalizes str::split_once().

fn split<'s>(&self, haystack: &'s str) -> impl Iterator<Item = &'s str>

Splits the given haystack. This generalizes str::split().

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
