Struct jaded::AnnotationIter

pub struct AnnotationIter<'a> { /* private fields */ }

Utility for reading things from annotations

This is intended to offer a similar interface to the ObjectInputStream used by Java classes that implement custom readObject methods.

Implementations

impl<'a> AnnotationIter<'a>

pub fn read_u8(&mut self) -> ConversionResult<u8>

Read byte from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readByte()

pub fn read_boolean(&mut self) -> ConversionResult<bool>

Read boolean from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readBoolean()

pub fn read_i16(&mut self) -> ConversionResult<i16>

Read short (i16) from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readShort()

pub fn read_i32(&mut self) -> ConversionResult<i32>

Read int (i32) from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readInt()

pub fn read_i64(&mut self) -> ConversionResult<i64>

Read long (i64) from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readLong()

pub fn read_f32(&mut self) -> ConversionResult<f32>

Read float (f32) from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readFloat()

pub fn read_f64(&mut self) -> ConversionResult<f64>

Read double (f64) from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.

See

ObjectInputStream#readDouble()

pub fn read_char(&mut self) -> ConversionResult<char>

Read char from annotation

Errors

ConversionError::InvalidType

• if there is not enough data
• if the next item in the annotation is an object instead of binary data.
• if the bytes are not a valid UTF-8 character

See

ObjectInputStream#readChar()

pub fn read_object(&mut self) -> ConversionResult<&'a Value>

Read an object from annotation

Errors

ConversionError::UnexpectedBlockData if the next item in annotation is binary data. ConversionError::MissingAnnotations if there are no more objects in this annotation

See

ObjectInputStream#readObject()

pub fn read_object_as<T: FromJava>(&mut self) -> ConversionResult<T>

Read an object and convert it to a rust type

Errors

This method is the equivalent of T::from_value(read_object()?) so any errors raised by either method will be returned.
