Struct BootMgr

pub struct BootMgr {
    pub boot_config: BootConfig,
    /* private fields */
}

The storage for configuration files.

Fields

boot_config: BootConfig

The configuration of the boot manager.

Implementations

impl BootMgr

pub fn new() -> BootResult<Self>

Creates a new BootMgr, load drivers, then populate it with Configs.

It will also add special boot options, like Reboot, Shutdown, and Reset to Firmware. This will also parse the main configuration file located at \\loader\\bootmgr-rs.conf for user settings.

Errors

May return an Error if a fatal error occurred when parsing the BootConfig (such as the image handle not supporting SimpleFileSystem) or when parsing the Configs.

pub fn load(&mut self, selected: usize) -> BootResult<Handle>

Load a boot option from a Config given the index.

Errors

May return an Error if an error occurred while loading the boot option.

pub const fn list(&self) -> &Vec<Config>

Returns a reference to the inner Vec<Config>.

pub const fn list_mut(&mut self) -> &mut Vec<Config>

Returns a mutable reference to the inner Vec<Config>.

pub fn get_config(&mut self, option: usize) -> &mut Config

Returns a mutable reference to an inner Config.

pub fn get_default(&self) -> usize

Gets the default boot option.

If the default boot option is not set, then 0 is returned

pub fn set_default(&self, option: usize)

Sets the default boot option by index.

This is stored in a UEFI variable. Due to the poor quality of how UEFI variables are stored sometimes, this cannot be completely reliable across all firmware implementations.

pub fn validate(&mut self)

Validates the inner Vec<Config> through various criteria.

If any of the Configs are found to be invalid, then they will be filtered.
