Struct SourceContext 

pub struct SourceContext { /* private fields */ }

Context for managing source files

Implementations

impl SourceContext

pub fn new() -> Self

Create a new empty source context

pub fn add_file(&mut self, path: String, content: Option<String>) -> FileId

Add a file to the context and return its ID

• If content is Some: Creates an ephemeral (in-memory) file. Content is stored and used for ariadne rendering.
• If content is None: Creates a disk-backed file. Content will be read from disk when needed (path must exist).

For ephemeral files, FileInformation is created immediately from the provided content. For disk-backed files, FileInformation is created by reading from disk if the path exists.

pub fn add_file_with_info( &mut self, path: String, file_info: FileInformation, ) -> FileId

Add a file with pre-computed FileInformation

This is useful when deserializing from formats (like JSON) that include serialized FileInformation, avoiding the need to recompute line breaks or read from disk.

The file is created without content (content=None), so ariadne rendering won’t work, but map_offset() will work using the provided FileInformation.

pub fn add_file_with_id( &mut self, id: FileId, path: String, content: Option<String>, ) -> FileId

Add a file with a specific FileId

This is useful when interfacing with systems that use hash-based or non-sequential FileIds (like quarto-yaml). The FileId must not already exist in the context.

Panics

Panics if the FileId already exists in the context.

pub fn get_file(&self, id: FileId) -> Option<&SourceFile>

Get a file by ID

pub fn without_content(&self) -> Self

Create a copy without FileInformation (for serialization)

Note: This preserves the content field for ephemeral files, as they need content to be serialized for proper deserialization. Only FileInformation is removed since it can be reconstructed from content.
