Variants

Null

No value (AOSP’s TYPE_NULL).

String(String)

A plain UTF-8 string.

BytesHex(Vec<u8>)

Bytes whose canonical text form is lowercase hex.

BytesBase64(Vec<u8>)

Bytes whose canonical text form is Base64.

Int(i32)

A 32-bit signed integer, rendered in decimal.

IntHex(u32)

A 32-bit value rendered in hex — see AttributeValue::as_str for the signed-magnitude rendering rule this follows.

Long(i64)

A 64-bit signed integer, rendered in decimal.

LongHex(u64)

A 64-bit value rendered in hex — see AttributeValue::as_str for the signed-magnitude rendering rule this follows.

Float(f32)

A 32-bit floating-point value.

Double(f64)

A 64-bit floating-point value.

Boolean(bool)

A boolean, rendered as "true"/"false".

Implementations

impl AttributeValue

pub fn as_str(&self) -> Cow<'_, str>

Render the value as a human-readable string, mirroring the original Java serializer’s output.

pub fn as_string(&self) -> Option<&str>

Returns the inner string if this is AttributeValue::String, else None.

pub fn as_int(&self) -> Option<i32>

Returns the inner value if this is AttributeValue::Int, else None.

pub fn as_int_hex(&self) -> Option<u32>

Returns the inner value if this is AttributeValue::IntHex, else None.

pub fn as_long(&self) -> Option<i64>

Returns the inner value if this is AttributeValue::Long, else None.

pub fn as_long_hex(&self) -> Option<u64>

Returns the inner value if this is AttributeValue::LongHex, else None.

pub fn as_float(&self) -> Option<f32>

Returns the inner value if this is AttributeValue::Float, else None.

pub fn as_double(&self) -> Option<f64>

Returns the inner value if this is AttributeValue::Double, else None.

pub fn as_bool(&self) -> Option<bool>

Returns the inner value if this is AttributeValue::Boolean, else None.

pub fn as_bytes(&self) -> Option<&[u8]>

Returns the inner bytes if this is AttributeValue::BytesHex or AttributeValue::BytesBase64, else None.

Trait Implementations
