Struct substrate::io::layout::OptionBuilder

pub struct OptionBuilder<T>(/* private fields */);

A simple builder that allows setting data at runtime.

let mut builder = OptionBuilder::default();
builder.set(5);
assert_eq!(builder.build().unwrap(), 5);

Implementations

impl<T> OptionBuilder<T>

pub fn new() -> Self

Constructs a new, empty OptionBuilder.

pub fn set(&mut self, inner: T)

Set the value of the data contained by the builder.

pub fn build(self) -> Result<T>

Returns the data contained by the builder.

Trait Implementations

impl<T: IsBundle> BundleBuilder<T> for OptionBuilder<T>

fn build(self) -> Result<T>

Builds an instance of bundle T.

impl<T: Clone> Clone for OptionBuilder<T>

fn clone(&self) -> OptionBuilder<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for OptionBuilder<T>

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

Formats the value using the given formatter.

impl<T> Default for OptionBuilder<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T: Hash> Hash for OptionBuilder<T>

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 HierarchicalBuildFrom<IndexMap<NameBuf, PortGeometry>> for OptionBuilder<IoShape>

fn build_from(&mut self, path: &mut NameBuf, source: &NamedPorts)

Build self from the given root path and source.

fn build_from_top(&mut self, source: &T)

Build self from the given source, starting with an empty top-level name buffer.

fn build_from_top_prefix(&mut self, prefix: impl Into<NameFragment>, source: &T)

Build self from the given source, starting with a top-level name buffer containing the given name fragment.

impl<T: PartialEq> PartialEq for OptionBuilder<T>

fn eq(&self, other: &OptionBuilder<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
