Struct DriverBuilder 

pub struct DriverBuilder { /* private fields */ }

Builder for configuring a Driver instance.

Use Driver::builder() to create a new builder.

Implementations

impl DriverBuilder

pub fn new() -> Self

Creates a new driver builder with no configuration.

pub fn binary(self, path: impl Into<PathBuf>) -> Self

Sets the path to the Firefox binary executable.

Arguments

• path - Path to Firefox binary (e.g., “/usr/bin/firefox”)

pub fn extension(self, path: impl Into<PathBuf>) -> Self

Sets the path to the WebDriver extension.

Automatically detects whether the path is a directory (unpacked) or file (packed .xpi).

Arguments

• path - Path to extension directory or .xpi file

pub fn extension_base64(self, data: impl Into<String>) -> Self

Sets the extension from a base64-encoded string.

Useful for embedding the extension in the binary.

Arguments

• data - Base64-encoded .xpi content

pub fn extension_source(self, source: ExtensionSource) -> Self

Sets the extension source directly.

Arguments

• source - Extension source variant

pub async fn build(self) -> Result<Driver>

Builds the driver with validation.

This is an async operation because it binds the WebSocket server.

Errors

• Error::Config if binary or extension not set
• Error::FirefoxNotFound if binary path doesn’t exist
• Error::Config if extension path doesn’t exist
• Error::Io if WebSocket server binding fails
