Struct object::write::elf::AttributesWriter

pub struct AttributesWriter { /* private fields */ }

A helper for writing an attributes section.

Attributes have a variable length encoding, so it is awkward to write them in a single pass. Instead, we build the entire attributes section data in memory, using placeholders for unknown lengths that are filled in later.

Implementations

impl AttributesWriter

pub fn new(endian: Endianness) -> Self

Create a new AttributesWriter for the given endianness.

pub fn start_subsection(&mut self, vendor: &[u8])

Start a new subsection with the given vendor name.

pub fn end_subsection(&mut self)

End the subsection.

The subsection length is automatically calculated and written.

pub fn start_subsubsection(&mut self, tag: u8)

Start a new sub-subsection with the given tag.

pub fn write_subsubsection_index(&mut self, index: u32)

Write a section or symbol index to the sub-subsection.

The user must also call this function to write the terminating 0 index.

pub fn write_subsubsection_indices(&mut self, indices: &[u8])

Write raw index data to the sub-subsection.

The terminating 0 index is automatically written.

pub fn write_attribute_tag(&mut self, tag: u64)

Write an attribute tag to the sub-subsection.

pub fn write_attribute_integer(&mut self, value: u64)

Write an attribute integer value to the sub-subsection.

pub fn write_attribute_string(&mut self, value: &[u8])

Write an attribute string value to the sub-subsection.

The value must not include the null terminator.

pub fn write_subsubsection_attributes(&mut self, attributes: &[u8])

Write raw attribute data to the sub-subsection.

pub fn end_subsubsection(&mut self)

End the sub-subsection.

The sub-subsection length is automatically calculated and written.

pub fn data(self) -> Vec<u8>

Return the completed section data.
