Struct Constrains 

pub struct Constrains {
    pub range: Range<Bound<String>>,
    pub total_digits: Option<usize>,
    pub fraction_digits: Option<usize>,
    pub patterns: Vec<String>,
    pub min_length: Option<usize>,
    pub max_length: Option<usize>,
    pub whitespace: WhiteSpace,
}

Constrains defined by the different facets of a type.

Fields

range: Range<Bound<String>>

Range the value should be in.

total_digits: Option<usize>

Number of total digits the value maximal should have.

fraction_digits: Option<usize>

Number of fraction digits the value maximal should have.

patterns: Vec<String>

Regex pattern the value should fulfill.

min_length: Option<usize>

The minimum length the value should have.

max_length: Option<usize>

The maximum length the value should have.

whitespace: WhiteSpace

Defines the whitespace handling.

Implementations

impl Constrains

pub fn need_value_validation(&self) -> bool

Returns true if this simple type needs value validation, false otherwise.

pub fn need_string_validation(&self) -> bool

Returns true if this simple type needs string validation, false otherwise.

Trait Implementations

impl Clone for Constrains

fn clone(&self) -> Constrains

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constrains

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

Formats the value using the given formatter.

impl Default for Constrains

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Constrains

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Constrains

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