Struct MainStyle 

pub struct MainStyle<M> {
    pub margin: Option<MarginStyle<M>>,
    pub horizontal_char: char,
    pub vertical_char: char,
    pub top_vertical_char: char,
    pub top_corner_char: char,
    pub bottom_corner_char: char,
    pub spaces_meta: M,
    pub text_normal_meta: M,
    pub text_alt_meta: M,
}

The general style of an annotated snippet.

This controls how the snippet and its annotations are drawn (margin, connector lines, corners) and which metadata is attached to each text fragment.

M is an output-backend-defined metadata type (often a “color/style”). It is passed through to Output.

Fields

margin: Option<MarginStyle<M>>

The style of the margin.

If None, there will not be any margin at all.

horizontal_char: char

Character used to draw the horizontal connectors of multi-line annotations.

vertical_char: char

Character used to draw the vertical connector of multi-line annotations.

top_vertical_char: char

Character used to draw the top corner of multi-line annotations that start at the first column.

top_corner_char: char

Character used to draw the top corner of multi-line annotations.

bottom_corner_char: char

Character used to draw the bottom corner of multi-line annotations.

spaces_meta: M

Metadata that accompanies spaces.

This is used for padding and separator spaces inserted by the renderer.

text_normal_meta: M

Metadata that accompanies unannotated text.

text_alt_meta: M

Metadata that accompanies unannotated alternate text.

“Alternate text” refers to replacement text emitted when the renderer makes normally-invisible or potentially-confusing source elements explicit (for example, certain control characters or invalid UTF-8 sequences, depending on snippet settings).

Trait Implementations

impl<M: Clone> Clone for MainStyle<M>

fn clone(&self) -> MainStyle<M>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<M: Debug> Debug for MainStyle<M>

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

Formats the value using the given formatter.

impl<M: PartialEq> PartialEq for MainStyle<M>

fn eq(&self, other: &MainStyle<M>) -> 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.
