Struct StringSchema 

pub struct StringSchema {
    pub constant: Option<String>,
    pub choices: Option<Vec<String>>,
    pub format: Option<StringFormat>,
    pub format_name: Option<String>,
    pub min_length: Option<usize>,
    pub max_length: Option<usize>,
    pub min_graphemes: Option<usize>,
    pub max_graphemes: Option<usize>,
}

A string schema and everything that constrains it.

Fields

constant: Option<String>

The only value permitted, if the schema names one.

choices: Option<Vec<String>>

The closed set of permitted values, if the schema names one.

Distinct from knownValues, which is open and is not enforced.

format: Option<StringFormat>

The declared format, if this build recognises it.

format_name: Option<String>

The format name as written, kept even when unrecognised so that an error can name it.

min_length: Option<usize>

Minimum length in UTF-8 bytes.

max_length: Option<usize>

Maximum length in UTF-8 bytes.

min_graphemes: Option<usize>

Minimum length in grapheme clusters.

max_graphemes: Option<usize>

Maximum length in grapheme clusters.

Trait Implementations

impl Clone for StringSchema

fn clone(&self) -> StringSchema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StringSchema

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

Formats the value using the given formatter.

impl Default for StringSchema

fn default() -> StringSchema

Returns the “default value” for a type.

impl PartialEq for StringSchema

fn eq(&self, other: &StringSchema) -> 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.
