Struct PartName 

pub struct PartName(/* private fields */);

Part 逻辑路径，形式如 /ppt/slides/slide1.xml。

字符串以 / 开头，不含 ..，以 / 分隔。NewType 包装确保 调用方不会“误用相对路径“。

Implementations

impl PartName

pub fn from_unchecked(s: impl Into<String>) -> Self

用裸路径字符串构造，不做合法性校验。

适用于内部已知合法的场景；外部输入请用 PartName::new。

pub fn new(s: &str) -> Result<Self, PartNameError>

校验并构造。

错误

• PartNameError::NotAbsolute：不以 / 开头；
• PartNameError::EmptySegment：含空段（双斜杠）；
• PartNameError::RelSegment：含 . 或 .. 段。

pub fn as_str(&self) -> &str

字符串视图。

pub fn into_string(self) -> String

取出内部字符串（消费 self）。

pub fn to_zip_path(&self) -> &str

转成 zip 内的相对路径（去掉前导 /）。

pub fn ext(&self) -> String

取扩展名（含 .，小写），无扩展名时为空串。

pub fn sibling(&self, filename: &str) -> PartName

同级目录下新文件名：取父目录，拼上 filename。

pub fn parent(&self) -> Option<PartName>

父目录 part name。已为根时返回 None。

Trait Implementations

impl Clone for PartName

fn clone(&self) -> PartName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartName

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

Formats the value using the given formatter.

impl Display for PartName

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

Formats the value using the given formatter.

impl Eq for PartName

impl FromStr for PartName

type Err = PartNameError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for PartName

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 Ord for PartName

fn cmp(&self, other: &PartName) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PartName

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

impl PartialOrd for PartName

fn partial_cmp(&self, other: &PartName) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
