Struct Signer 

pub struct Signer { /* private fields */ }

Signs APKs with one or more identities.

Like apksigner, the schemes default to Schemes::for_min_sdk, and the minimum and target API levels are read from the APK’s manifest unless the minimum is set explicitly.

Implementations

impl Signer

pub fn new(identity: SigningIdentity) -> Self

pub fn with_signer(self, identity: SigningIdentity) -> Self

Adds another signer (v1 and v2 only).

pub fn min_sdk(self, min_sdk: ApiLevel) -> Self

The oldest Android release the APK must install on, overriding the manifest’s minSdkVersion. This selects the default schemes and the JAR digest.

pub fn schemes(self, schemes: Schemes) -> Self

Overrides the default schemes.

pub fn native_library_page_size(self, page_size: PageSize) -> Self

The page size stored native libraries are aligned to when re-signing an existing APK (default 16 KiB).

pub fn identities(&self) -> &[SigningIdentity]

pub fn sign_file(&self, path: impl AsRef<Path>) -> Result<(), Error>

Signs the APK at path in place. The file is replaced atomically, and left untouched if signing fails.

pub fn sign( &self, input: impl AsRef<Path>, output: impl AsRef<Path>, ) -> Result<(), Error>

Signs input into output (which may be the same path). Existing signatures are replaced, stored entries are realigned (native libraries to pages, everything else to 4 bytes), and compressed data is copied without recompressing it.

Trait Implementations

impl Clone for Signer

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Signer

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

Formats the value using the given formatter.
