Struct samply_symbols::CompactSymbolTable

pub struct CompactSymbolTable {
    pub addr: Vec<u32>,
    pub index: Vec<u32>,
    pub buffer: Vec<u8>,
}

A “compact” representation of a symbol table. This is a legacy concept used by the Firefox profiler and kept for compatibility purposes. It’s called SymbolTableAsTuple in the profiler code.

The string for the address addrs[i] is std::str::from_utf8(buffer[index[i] as usize .. index[i + 1] as usize])

Fields

addr: Vec<u32>

A sorted array of symbol addresses, as library-relative offsets in bytes, in ascending order.

index: Vec<u32>

Contains positions into buffer. For every address addr[i], index[i] is the position where the string for that address starts in the buffer. Also contains one extra index at the end which is buffer.len(). index.len() == addr.len() + 1

buffer: Vec<u8>

A buffer of bytes that contains all strings from this symbol table, in the order of the addresses they correspond to, in utf-8 encoded form, all concatenated together.

Implementations

impl CompactSymbolTable

pub fn from_symbol_map<FL: FileLocation>(map: &SymbolMap<FL>) -> Self
