Source 
#[unsafe(no_mangle)]

    env_data: *const Value,
    env_len: usize,
    index: i32,
) -> i64
Expand description

Get a Quotation impl_ function pointer from the closure environment

Returns i64 (the impl_ function pointer as usize) for LLVM IR. Returns the tailcc impl_ pointer for TCO when called from compiled code. Quotations are stateless, so only the function pointer is needed.

ยงSafety

  • env_data must be a valid pointer to an array of Values
  • env_len must match the actual array length
  • index must be in bounds [0, env_len)
  • The value at index must be Value::Quotation
