Enum InputMask 

pub enum InputMask {
    Numeric,
    Alphanumeric,
}

Restricts which characters a text input accepts.

Apply an InputMask to a Semantics node to filter keystrokes before they reach the text editing logic.

Variants

Numeric

Accept only ASCII digits (0-9).

Alphanumeric

Accept only ASCII letters and digits (a-z, A-Z, 0-9).

Implementations

impl InputMask

pub fn is_valid_char(&self, ch: char) -> bool

Returns true if ch is accepted by this mask.

Example

use fission_ir::semantics::InputMask;
assert!(InputMask::Numeric.is_valid_char('5'));
assert!(!InputMask::Numeric.is_valid_char('a'));

Trait Implementations

impl Clone for InputMask

fn clone(&self) -> InputMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InputMask

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InputMask

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for InputMask

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 InputMask

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

impl Serialize for InputMask

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for InputMask
