Struct DexReader 

pub struct DexReader {
    pub bytes: Cursor<Vec<u8>>,
    pub bytes_len: u64,
    pub endianness: DexEndianness,
}

A reader for a DEX file

Fields

bytes: Cursor<Vec<u8>>

A cursor over the bytes of the DEX file

bytes_len: u64

Number of bytes in the DEX file

endianness: DexEndianness

Endianness of the DEX file

Implementations

impl DexReader

pub fn build_from_file(filepath: &str) -> Result<Vec<DexReader>, DexError>

Open the file at the given path and create reader(s)

Each APK can contain multiple DEX files. This function extracts them all, create a reader from each, and returns a vector of readers.

pub fn build(raw_dex: Vec<u8>) -> Result<Self, DexError>

Read a DEX file and create a reader from it

pub fn check_endianness(bytes: &[u8]) -> Result<DexEndianness, DexError>

Check the endianness of a DEX file

pub fn align_cursor(&mut self) -> Result<(), DexError>

Check if the cursor is on an even-numbered bytecode offsets and, if not, consume data until it is

pub fn read_u8(&mut self) -> Result<u8, DexError>

Read an unsigned 8 bits integer from the reader

pub fn read_u16(&mut self) -> Result<u16, DexError>

Read an unsigned 16 bits integer from the reader

pub fn read_u32(&mut self) -> Result<u32, DexError>

Read an unsigned 32 bits integer from the reader

pub fn read_i32(&mut self) -> Result<i32, DexError>

Read a signed 32 bits integer from the reader

pub fn read_uleb128(&mut self) -> Result<(u32, usize), DexError>

Read an unsigned LEB128 value from the reader

pub fn read_sleb128(&mut self) -> Result<(i32, usize), DexError>

Read a signed LEB128 value from the reader

pub fn read_uleb128p1(&mut self) -> Result<(i32, usize), DexError>

Read a signed LEB128p1 value from the reader

Trait Implementations

impl Debug for DexReader

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

Formats the value using the given formatter.
