LocalHeap

Struct LocalHeap 

Source
pub struct LocalHeap {
    pub data_segment_size: u64,
    pub free_list_offset: u64,
    pub data_segment_address: u64,
}
Expand description

A parsed HDF5 local heap header.

The data segment (containing the actual strings) is stored separately in the file at data_segment_address.

Fields§

§data_segment_size: u64

Size in bytes of the data segment.

§free_list_offset: u64

Offset to the head of the free-list within the data segment (relative to the start of the data segment).

§data_segment_address: u64

Absolute file address of the data segment.

Implementations§

Source§

impl LocalHeap

Source

pub fn parse( cursor: &mut Cursor<'_>, offset_size: u8, length_size: u8, ) -> Result<Self>

Parse a local heap header at the current cursor position.

Format:

  • Signature: HEAP (4 bytes)
  • Version: 0 (1 byte)
  • Reserved: 3 bytes
  • Data segment size (length_size bytes)
  • Offset to head of free list (length_size bytes)
  • Data segment address (offset_size bytes)
Source

pub fn get_string(&self, offset: u64, file_data: &[u8]) -> Result<String>

Read a null-terminated string at the given offset within the heap’s data segment.

offset is relative to the start of the data segment (as stored in SymbolTableEntry::link_name_offset). file_data must be the entire file (or at least the portion containing the data segment).
