Struct AttrDef 

pub struct AttrDef { /* private fields */ }

A public framework attribute.

Implementations

impl AttrDef

pub const fn name(&self) -> &'static str

The attribute name without its android: prefix.

pub const fn id(&self) -> ResourceId

pub fn format(&self) -> AttrFormat

The accepted formats; AttrFormat::ANY when undeclared.

pub fn accepts(&self, value: &Value) -> bool

Whether value has a format this attribute accepts, as aapt2 would have typed it. References, @null, @empty, and values of types this crate does not interpret are resolved at runtime, so they are always accepted.

use apk::android::attr;
use apk::res::Value;

assert!(attr::HAS_CODE.accepts(&Value::Bool(false)));
assert!(!attr::HAS_CODE.accepts(&Value::String("false".into())));
assert!(attr::SCREEN_ORIENTATION.accepts(&Value::Int(0)));

pub const fn symbols(&self) -> &'static [Symbol]

The enum or flag values this attribute defines.

pub fn symbol(&self, name: &str) -> Option<u32>

The value of the enum or flag named name.

pub fn enum_name(&self, value: u32) -> Option<&'static str>

The name of the enum value value.

pub fn flag_names(&self, value: u32) -> Option<Vec<&'static str>>

Names the flags set in value, if value is exactly a union of them.

impl AttrDef

pub fn parse(&self, text: &str) -> Result<Value, XmlError>

Types text by the formats this attribute accepts, as aapt2 does:

use apk::android::attr;
use apk::res::Value;

assert_eq!(attr::SCREEN_ORIENTATION.parse("landscape")?, Value::Int(0));
assert_eq!(attr::CONFIG_CHANGES.parse("orientation|screenSize")?, Value::Hex(0x480));
assert_eq!(attr::EXPORTED.parse("true")?, Value::Bool(true));
assert!(attr::EXPORTED.parse("yes").is_err());
