Struct InputTextCallback

pub struct InputTextCallback { /* private fields */ }

Callback flags for an InputText widget. These correspond to the general textflags.

Implementations

impl InputTextCallback

pub const COMPLETION: InputTextCallback

Call user function on pressing TAB (for completion handling)

pub const HISTORY: InputTextCallback

Call user function on pressing Up/Down arrows (for history handling)

pub const ALWAYS: InputTextCallback

Call user function every time. User code may query cursor position, modify text buffer.

pub const CHAR_FILTER: InputTextCallback

Call user function to filter character.

pub const EDIT: InputTextCallback

Callback on buffer edit (note that InputText already returns true on edit, the callback is useful mainly to manipulate the underlying buffer while focus is active)

pub const fn empty() -> InputTextCallback

Returns an empty set of flags.

pub const fn all() -> InputTextCallback

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u32) -> Option<InputTextCallback>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u32) -> InputTextCallback

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u32) -> InputTextCallback

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

Safety

The caller of the bitflags! macro can chose to allow or disallow extra bits for their bitflags type.

The caller of from_bits_unchecked() has to ensure that all bits correspond to a defined flag or that extra bits are valid for this bitflags type.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: InputTextCallback) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: InputTextCallback) -> bool

Returns true if all of the flags in other are contained within self.

pub fn insert(&mut self, other: InputTextCallback)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: InputTextCallback)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: InputTextCallback)

Toggles the specified flags in-place.

pub fn set(&mut self, other: InputTextCallback, value: bool)

Inserts or removes the specified flags depending on the passed value.

pub const fn intersection(self, other: InputTextCallback) -> InputTextCallback

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: InputTextCallback) -> InputTextCallback

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both (see Self::symmetric_difference if that is undesirable).

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: InputTextCallback) -> InputTextCallback

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.

pub const fn symmetric_difference( self, other: InputTextCallback, ) -> InputTextCallback

Returns the symmetric difference between the flags in self and other.

Specifically, the returned set contains the flags present which are present in self or other, but that are not present in both. Equivalently, it contains the flags present in exactly one of the sets self and other.

This is equivalent to using the ^ operator (e.g. ops::BitXor), as in flags ^ other.

pub const fn complement(self) -> InputTextCallback

Returns the complement of this set of flags.

Specifically, the returned set contains all the flags which are not set in self, but which are allowed for this type.

Alternatively, it can be thought of as the set difference between Self::all() and self (e.g. Self::all() - self)

This is equivalent to using the ! operator (e.g. ops::Not), as in !flags.
