Struct HostPattern 

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

A validated host pattern from [[network.additional_hosts]].

Construction goes through HostPattern::new (or the TryFrom<&str> / TryFrom<String> impls), which run validate_pattern internally. The serde Deserialize impl also goes through TryFrom<String>, so any path that produces a HostPattern value — including TOML deserialisation — has passed validation. The invariant “this is a syntactically valid ADR-0028 D2-1 pattern” is therefore type-level.

Implementations

impl HostPattern

pub fn new(raw: impl Into<String>) -> Result<Self, PatternError>

Construct after validation. Most callers prefer the TryFrom impls.

Errors

Returns PatternError for any input that fails validate_pattern.

pub fn as_str(&self) -> &str

Borrow the validated pattern as a &str.

Trait Implementations

impl Clone for HostPattern

fn clone(&self) -> HostPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HostPattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HostPattern

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Hash for HostPattern

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 PartialEq for HostPattern

fn eq(&self, other: &HostPattern) -> 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 TryFrom<&str> for HostPattern

type Error = PatternError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for HostPattern

type Error = PatternError

The type returned in the event of a conversion error.

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

Performs the conversion.
