Struct Extensions 

pub struct Extensions { /* private fields */ }

Collection of RISC-V extensions.

Implementations

impl Extensions

pub fn extensions(&self) -> Vec<Extension>

Returns a vector with the list of extensions. Extensions are sorted in canonical order.

The canonical order is defined as follows:

1. Base ISA (I or E)
2. Standard non-base extensions (M, A, F, D, Q, C, B, P, V, H)
3. Standard Z-type extensions (e.g., Zicsr)
4. Standard S-type extensions (e.g., Ssccfg)
5. Vendor X-type extensions (e.g., XSifivecdiscarddlone)

Z, S, and X-type extensions are sorted by their string representation.

pub fn base_extension(&self) -> Option<Extension>

Returns the base extension (I or E) if present.

pub fn contains(&self, extension: &Extension) -> bool

Returns true if the collection contains the given extension.

pub fn is_g(&self) -> bool

pub fn insert(&mut self, extension: Extension) -> bool

Adds an extension to the collection. Returns true if the extension was not present.

pub fn remove(&mut self, extension: &Extension) -> bool

Removes an extension from the collection. Returns true if the extension was present.

Trait Implementations

impl Clone for Extensions

fn clone(&self) -> Extensions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Extensions

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

Formats the value using the given formatter.

impl Display for Extensions

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

Formats the value using the given formatter.

impl PartialEq for Extensions

fn eq(&self, other: &Extensions) -> 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<'a> TryFrom<&'a str> for Extensions

type Error = Error<'a>

The type returned in the event of a conversion error.

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

Performs the conversion.
