Struct StringFilter 

pub struct StringFilter(/* private fields */);

A string filter that normalizes the string prior to consumption.

Normalizations:

• trims whitespace
• case-insensitive
• NFC normalizes

Implementations

impl StringFilter

pub fn any() -> Self

Create a string filter which will match anything

pub fn new(value: impl AsRef<str>) -> Self

Create a new string filter.

pub fn inner(&self) -> &str

Get the inner string.

pub fn into_inner(self) -> String

Convert the string filter into the inner string.

pub fn is_any(&self) -> bool

Return true if this value is considered an “any” value
