Struct Segment 

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

One address label — a validated, non-empty, separator-free token.

Constructed only through Segment::parse; see the module docs for the charset rule and why it is narrow.

Implementations

impl Segment

pub fn parse(s: &str) -> Result<Self, SegmentError>

The single fallible constructor. Rules are checked in the order documented on SegmentError’s arms, so the error names the most specific failure (ContainsSeparator beats a generic “illegal character”).

pub fn as_str(&self) -> &str

Borrow the validated label.

Trait Implementations

impl Clone for Segment

fn clone(&self) -> Segment

Returns a duplicate of the value.

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

impl Eq for Segment

impl From<Segment> for String

fn from(v: Segment) -> Self

Converts to this type from the input type.

impl FromStr for Segment

type Err = SegmentError

The associated error which can be returned from parsing.

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

impl Ord for Segment

fn cmp(&self, other: &Segment) -> 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,

impl StructuralPartialEq for Segment

impl TryFrom<String> for Segment

type Error = SegmentError

The type returned in the event of a conversion error.

fn try_from(s: String) -> Result<Self, Self::Error>

Performs the conversion.
