Trait for querying resolved style properties by index.

This is the bridge between format-specific style stores and format-independent consumers (like the Markdown encoder). Each method takes a branded index and returns Option<T>, where None means the property is unavailable or unsupported.

Default Implementations

Every method defaults to None, so an empty implementation is valid:

use hwpforge_core::StyleLookup;
use hwpforge_foundation::CharShapeIndex;

struct NoopStore;
impl StyleLookup for NoopStore {}

let store = NoopStore;
assert!(store.char_bold(CharShapeIndex::new(0)).is_none());

Provided Methods

fn char_bold(&self, _id: CharShapeIndex) -> Option<bool>

Returns whether the character shape at id is bold.

fn char_italic(&self, _id: CharShapeIndex) -> Option<bool>

Returns whether the character shape at id is italic.

fn char_underline(&self, _id: CharShapeIndex) -> Option<UnderlineType>

Returns the underline type of the character shape at id.

fn char_strikeout(&self, _id: CharShapeIndex) -> Option<bool>

Returns whether the character shape at id has strikeout.

fn char_superscript(&self, _id: CharShapeIndex) -> Option<bool>

Returns whether the character shape at id is superscript.

fn char_subscript(&self, _id: CharShapeIndex) -> Option<bool>

Returns whether the character shape at id is subscript.

fn char_font_name(&self, _id: CharShapeIndex) -> Option<&str>

Returns the font name of the character shape at id.

fn char_font_size(&self, _id: CharShapeIndex) -> Option<HwpUnit>

Returns the font size (in HwpUnit) of the character shape at id.

fn char_text_color(&self, _id: CharShapeIndex) -> Option<Color>

Returns the text color of the character shape at id.

fn para_alignment(&self, _id: ParaShapeIndex) -> Option<Alignment>

Returns the horizontal alignment of the paragraph shape at id.

fn para_indent_left(&self, _id: ParaShapeIndex) -> Option<HwpUnit>

Returns the left indent of the paragraph shape at id.

fn para_indent_first_line(&self, _id: ParaShapeIndex) -> Option<HwpUnit>

Returns the first-line indent of the paragraph shape at id.

fn para_list_type(&self, _id: ParaShapeIndex) -> Option<&str>

Returns the list type for a paragraph shape: "BULLET", "NUMBER", or None.

Returns None if the paragraph has no list heading or if the heading type is NONE / OUTLINE.

fn para_list_level(&self, _id: ParaShapeIndex) -> Option<u8>

Returns the zero-based list nesting level for a paragraph shape.

This is only meaningful for numbered/bulleted list semantics. Outline headings should use para_heading_level instead.

fn para_checked_state(&self, _id: ParaShapeIndex) -> Option<bool>

Returns the checkbox state for a paragraph shape when it is a checkable bullet.

Some(true) means a checked checkbox item, Some(false) means an unchecked checkbox item, and None means the paragraph is not a checkable bullet.

fn para_style_name(&self, _id: ParaShapeIndex) -> Option<&str>

Returns the preferred style name associated with the paragraph shape.

This is useful for encoders that need to recover semantics carried by a dedicated paragraph shape even when the paragraph itself has no explicit style_id.

fn para_heading_level(&self, _id: ParaShapeIndex) -> Option<u8>

Returns the heading level (1–6) implied by the paragraph shape at id.

This is the format-agnostic truth source for paragraph-level outline semantics. Implementors that can inspect real paragraph-shape outline metadata should override this method; downstream styled export paths use it before style-name heuristics whenever both are available.

fn style_name(&self, _id: StyleIndex) -> Option<&str>

Returns the Korean name of the style at id.

fn style_heading_level(&self, _id: StyleIndex) -> Option<u8>

Returns the heading level (1–6) of the style at id, if it is a heading style. Returns None for non-heading styles.

fn image_resolve_filename(&self, _key: &str) -> Option<&str>

Resolves a binaryItemIDRef (e.g. "BinData/image1") to the actual filename with extension (e.g. "image1.png").

Returns None if no matching image is found.

fn image_data(&self, _key: &str) -> Option<&[u8]>

Returns the raw binary data for the image identified by key.

key is typically a path like "image1.jpg". Returns None if the image is not available or if the implementor does not store image data.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
