Implementations

impl Requirement

pub fn icon(&self) -> &'static str

Emoji icon for hardware requirements.

pub fn label(&self) -> &'static str

Human-readable hardware label.

pub fn from_display_name(name: &str) -> Option<Self>

Parse a requirement from its Display name (inverse of to_string()).

pub fn icon_for_display_name(name: &str) -> &'static str

Look up the icon for a requirement by its Display name.

This is the canonical mapping used by CLI/TUI code that only has the serialised string form (e.g. from [SourceInfoSnapshot]).

pub fn label_for_display_name(name: &str) -> &'static str

Look up the label for a requirement by its Display name.

Returns the human-readable label if the name is recognised, or a generic "Unknown" for unrecognised names.

Trait Implementations

impl Clone for Requirement

fn clone(&self) -> Requirement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Requirement

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

Formats the value using the given formatter.

impl Display for Requirement

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

Formats the value using the given formatter.

impl Hash for Requirement

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 Requirement

fn eq(&self, other: &Requirement) -> 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 Copy for Requirement

impl Eq for Requirement

impl StructuralPartialEq for Requirement
