Struct InputTrie 

pub struct InputTrie { /* private fields */ }

Represents a prefix trie based on input paths.

This is used to determine guest paths for inputs.

From the root to a terminal node represents a unique input.

Implementations

impl InputTrie

pub fn new() -> Self

Constructs a new inputs trie without a guest inputs directory.

Terminal nodes in the trie will not be mapped to guest paths.

pub fn new_with_guest_dir(guest_inputs_dir: &'static str) -> Self

Constructs a new inputs trie with a guest inputs directory.

Inputs with a host path will be mapped to a guest path relative to the guest inputs directory.

Note: a guest inputs directory is always a Unix-style path.

Panics

Panics if the guest inputs directory does not end with a slash.

pub fn insert( &mut self, kind: ContentKind, path: &str, base_dir: &EvaluationPath, ) -> Result<Option<usize>>

Inserts a new input into the trie.

The path is either a local or remote input path.

Relative paths are made absolute via the provided base path.

If an input was added, returns Ok(Some(index)) where index is the index of the input in the trie.

Returns Ok(None) if the provided path was already a guest input path.

Returns an error for an invalid input path.

pub fn as_slice(&self) -> &[Input]

Gets the inputs of the trie as a slice.

pub fn as_slice_mut(&mut self) -> &mut [Input]

Gets the inputs of the trie as a mutable slice.

Trait Implementations

impl Debug for InputTrie

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

Formats the value using the given formatter.
