Struct loro_internal::container::richtext::TextStyleInfoFlag

pub struct TextStyleInfoFlag { /* private fields */ }

A compact representation of a rich text style config.

Note: we assume style with the same key has the same Mergeable and isContainer value.

• Mergeable (1st bit): whether two styles with the same key can be merged into one.
• Expand Before (2nd bit): when inserting new text before this style, whether the new text should inherit this style.
• Expand After (3rd bit): when inserting new text after this style, whether the new text should inherit this style.
• Delete (4th bit): whether this is used to remove a style from a range.
• isContainer (5th bit): whether the style also store other data in a associated map container with the same OpID.
• 0 (6th bit)
• 0 (7th bit)
• isAlive (8th bit): always 1 unless the style is garbage collected. If this is 0, all other bits should be 0 as well.

Implementations

impl TextStyleInfoFlag

pub fn mergeable(self) -> bool

Whether two styles with the same key can be merged into one. If false, the styles will coexist in the same range.

pub fn expand_before(self) -> bool

When inserting new text around this style, prefer inserting after it.

pub fn expand_after(self) -> bool

When inserting new text around this style, prefer inserting before it.

pub fn prefer_insert_before(self, anchor_type: AnchorType) -> bool

This method tells that when we can insert text before/after this style anchor, whether we insert the new text before the anchor.

pub fn is_delete(&self) -> bool

pub fn is_container(&self) -> bool

pub const fn new( mergeable: bool, expand_type: ExpandType, is_delete: bool, is_container: bool ) -> Self

pub const fn is_dead(self) -> bool

pub const fn to_delete(self) -> Self

pub const BOLD: TextStyleInfoFlag = _

pub const LINK: TextStyleInfoFlag = _

pub const COMMENT: TextStyleInfoFlag = _

pub const fn to_byte(&self) -> u8

pub const fn from_byte(data: u8) -> Self

Trait Implementations

impl Clone for TextStyleInfoFlag

fn clone(&self) -> TextStyleInfoFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextStyleInfoFlag

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

Formats the value using the given formatter.

impl Default for TextStyleInfoFlag

fn default() -> TextStyleInfoFlag

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TextStyleInfoFlag

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for TextStyleInfoFlag

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 TextStyleInfoFlag

fn eq(&self, other: &TextStyleInfoFlag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for TextStyleInfoFlag

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

Serialize this value into the given Serde serializer.
