pub struct CharacterLimits { /* private fields */ }

Character limits configuration for a field

Implementations

impl CharacterLimits

pub fn new(max_length: usize) -> Self

Create new character limits with just max length

pub fn new_range(min_length: usize, max_length: usize) -> Self

Create new character limits with min and max

pub fn new_min(min_length: usize) -> Self

Create new character limits with just minimum length

pub fn new_warning(threshold: usize) -> Self

Create new character limits with only a warning threshold.

pub fn with_warning_threshold(self, threshold: usize) -> Self

Set warning threshold (when to show warning before hitting limit)

pub fn with_count_mode(self, mode: CountMode) -> Self

Set count mode (characters vs display width vs bytes)

pub fn max_length(&self) -> Option<usize>

Get maximum length

pub fn min_length(&self) -> Option<usize>

Get minimum length

pub fn warning_threshold(&self) -> Option<usize>

Get warning threshold

pub fn count_mode(&self) -> CountMode

Get count mode

pub fn validate_insertion( &self, current_text: &str, position: usize, character: char, ) -> Option<ValidationResult>

Check if inserting a character would exceed limits

pub fn validate_content(&self, text: &str) -> Option<ValidationResult>

Validate the current content

pub fn check_limits(&self, text: &str) -> LimitCheckResult

Get the current status of the text against limits

pub fn status_text(&self, text: &str) -> Option<String>

Get a human-readable status string

pub fn allows_field_switch(&self, text: &str) -> bool

pub fn field_switch_block_reason(&self, text: &str) -> Option<String>

Get reason why field switching is not allowed (if any)
