Struct tbf::InMemoryFs

pub struct InMemoryFs { /* fields omitted */ }

An in-memory implementation of a tag-based filesystem. This implementation will store all data in program memory, only persisting it for the duration of the program runtime.

This is most useful for tests / mocking of a filesystem, and probably not what you want for long term usage.

Implementations

impl InMemoryFs

pub fn new() -> InMemoryFs

Create a new instance of an in-memory filesystem

Trait Implementations

impl Default for InMemoryFs

fn default() -> Self

Returns the “default value” for a type.

impl FileSystem for InMemoryFs

type Error = Error

The error type to use with this filesystem.

fn add_file<I>(&self, data: &[u8], tags: I) -> Result<FileId, Self::Error> where
    I: IntoIterator<Item = Tag>, 

Add a new file with the given data and tags

fn edit_file<I>(
    &self,
    id: FileId,
    data: Option<&[u8]>,
    tags: Option<I>
) -> Result<(), Self::Error> where
    I: IntoIterator<Item = Tag>, 

Edit an existing file, altering the data or tags

fn remove_file(&self, id: FileId) -> Result<(), Self::Error>

Remove an existing file

fn search_tags<P>(&self, tags: P) -> Result<Vec<FileId>, Self::Error> where
    P: TagPattern, 

Search for files matching a given tag pattern

fn get_info(&self, id: FileId) -> Result<FileInfo, Self::Error>
