Struct artichoke_backend::load_path::Hybrid[][src]

pub struct Hybrid { /* fields omitted */ }

Implementations

Create a new hybrid virtual filesystem.

This filesystem allows access to the host filesystem with an in-memory filesystem mounted at RUBY_LOAD_PATH.

Check whether path points to a file in the virtual filesystem and return the absolute path if it exists.

This API is infallible and will return None for non-existent paths.

Check whether path points to a file in the virtual filesystem.

This API is infallible and will return false for non-existent paths.

Read file contents for the file at path.

Returns a byte slice of complete file contents. If path is relative, it is absolutized relative to the current working directory of the virtual file system.

Errors

If path does not exist, an io::Error with error kind io::ErrorKind::NotFound is returned.

Write file contents into the virtual file system at path.

Writes the full file contents. If any file contents already exist at path, they are replaced. Extension hooks are preserved.

Only the Memory filesystem at RUBY_LOAD_PATH is writeable.

Errors

If access to the Memory filesystem returns an error, the error is returned. See Memory::write_file.

Retrieve an extension hook for the file at path.

This API is infallible and will return None for non-existent paths.

Write extension hook into the virtual file system at path.

If any extension hooks already exist at path, they are replaced. File contents are preserved.

This function writes all extensions to the virtual filesystem. If the given path does not map to the virtual filesystem, the extension is unreachable.

Errors

If the given path does not resolve to the virtual filesystem, an error is returned.

Check whether a file at path has been required already.

This API is infallible and will return false for non-existent paths.

Mark a source at path as required on the interpreter.

This metadata is used by Kernel#require and friends to enforce that Ruby sources are only loaded into the interpreter once to limit side effects.

Errors

If path does not exist, an io::Error with error kind io::ErrorKind::NotFound is returned.
