Struct fuchsia_zbi::ZbiParser

pub struct ZbiParser { /* private fields */ }

Implementations

impl ZbiParser

pub fn align_zbi_item(length: u32) -> Result<u32, ZbiParserError>

pub fn new(vmo: Vmo) -> ZbiParser

pub fn set_store_item(self, zbi_type: ZbiType) -> Self

Set a ZBI item type as should be stored. If no item types are set to store, then all known items are stored.

pub fn try_get_item( &self, zbi_type_raw: u32, extra: Option<u32>, ) -> Result<Vec<ZbiResult>, ZbiParserError>

Try and get one stored item type, optionally restricted by the item’s extra. The raw type is passed to allow differentiating between different types of driver metadata.

pub fn try_get_last_matching_item( &self, zbi_type_raw: u32, extra: u32, ) -> Result<ZbiResult, ZbiParserError>

Helper function to return the last item matching a given type and extra value. This avoids reading unwanted results from the underlying VMO. The raw type is passed to allow differentiating between different types of driver metadata.

pub fn get_items( &self, ) -> Result<HashMap<ZbiType, Vec<ZbiResult>>, ZbiParserError>

Get all stored ZBI items.

pub fn release_item(&mut self, zbi_type: ZbiType) -> Result<(), ZbiParserError>

Release an item type, zeroing the VMO memory and decommitting the pages if possible.

pub fn parse(self) -> Result<Self, ZbiParserError>

Parse a ZBI VMO, storing the offset for each item. If set_store_item was used, only those item types will be stored, and the other item types will be zeroed and decommitted.

Trait Implementations

impl Debug for ZbiParser

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
