Struct casper_node::utils::WithDir

pub struct WithDir<T> { /* private fields */ }

With-directory context.

Associates a type with a “working directory”.

Implementations

impl<T> WithDir<T>

pub fn new<P: Into<PathBuf>>(path: P, value: T) -> Self

Creates a new with-directory context.

pub fn dir(&self) -> &Path

Returns a reference to the inner path.

pub fn map_ref<U, F: FnOnce(&T) -> U>(&self, f: F) -> WithDir<U>

Maps an internal value onto a reference.

pub fn value(&self) -> &T

Get a reference to the inner value.

pub fn value_mut(&mut self) -> &mut T

Get a mutable reference to the inner value.

pub fn with_dir(&self, path: PathBuf) -> PathBuf

Adds self.dir as a parent if path is relative, otherwise returns path unchanged.

Trait Implementations

impl<T: Clone> Clone for WithDir<T>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> DataSize for WithDir<T>

where T: DataSize,

const IS_DYNAMIC: bool = _

If true, the type has a heap size that can vary at runtime, depending on the actual value.

const STATIC_HEAP_SIZE: usize = _

The amount of space a value of the type always occupies. If IS_DYNAMIC is false, this is the total amount of heap memory occupied by the value. Otherwise this is a lower bound.

fn estimate_heap_size(&self) -> usize

Estimates the size of heap memory taken up by this value.

fn estimate_detailed_heap_size(&self) -> MemUsageNode

Create a tree of memory estimations.

impl<T: Debug> Debug for WithDir<T>

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

Formats the value using the given formatter.
