Implementations

impl CameraPreset

pub fn as_str(&self) -> &str

转 OOXML 字符串。

pub fn parse(s: &str) -> CameraPreset

从字符串解析（不区分大小写、未识别则归入 Other）。

注：方法名为 parse 而非 from_str，以避免与 std::str::FromStr trait 冲突。

Trait Implementations

impl Clone for CameraPreset

fn clone(&self) -> CameraPreset

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CameraPreset

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

Formats the value using the given formatter.

impl Default for CameraPreset

fn default() -> CameraPreset

Returns the “default value” for a type.

impl Eq for CameraPreset

impl PartialEq for CameraPreset

fn eq(&self, other: &CameraPreset) -> 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.
