Crate cairo_native_runtime

Structs

• DICT_GAS_REFUND_PER_ACCESS
• FeltDict
  Felt252 type used in cairo native runtime
• FormattedItem
  A formatted string representation of anything formattable (e.g. ByteArray, felt, short-string).
• HALF_PRIME

Constants

• BYTES_IN_WORD
• BYTE_ARRAY_MAGIC

Functions

• as_cairo_short_string
  Converts a bigint representing a felt252 to a Cairo short-string.
• as_cairo_short_string_ex
  Converts a bigint representing a felt252 to a Cairo short-string of the given length. Nulls are allowed and length must be <= 31.
• cairo_native__dict_drop^⚠
  Free a dictionary using an optional callback to drop each element.
• cairo_native__dict_dup^⚠
  Duplicate a dictionary using a provided callback to clone each element.
• cairo_native__dict_gas_refund^⚠
  Compute the total gas refund for the dictionary at squash time.
• cairo_native__dict_get^⚠
  Return a pointer to the entry’s value pointer for a given key, inserting a null pointer if not present. Increment the access count.
• cairo_native__dict_new^⚠
  Allocate a new dictionary.
• cairo_native__get_costs_builtin
  Get the gas builtin from the internal thread local.
• cairo_native__libfunc__debug__print^⚠
  Based on cairo-lang-runner’s implementation.
• cairo_native__libfunc__ec__ec_point_from_x_nz^⚠
  Compute ec_point_from_x_nz(x) and store it.
• cairo_native__libfunc__ec__ec_point_try_new_nz^⚠
  Compute ec_point_try_new_nz(x).
• cairo_native__libfunc__ec__ec_state_add^⚠
  Compute ec_state_add(state, point) and store the state back.
• cairo_native__libfunc__ec__ec_state_add_mul^⚠
  Compute ec_state_add_mul(state, scalar, point) and store the state back.
• cairo_native__libfunc__ec__ec_state_init^⚠
  Compute ec_state_init() and store the state back.
• cairo_native__libfunc__ec__ec_state_try_finalize_nz^⚠
  Compute ec_state_try_finalize_nz(state) and store the result.
• cairo_native__libfunc__hades_permutation^⚠
  Compute hades_permutation(op0, op1, op2) and replace the operands with the results.
• cairo_native__libfunc__pedersen^⚠
  Compute pedersen(lhs, rhs) and store it into dst.
• cairo_native__set_costs_builtin
  Store the gas builtin in the internal thread local. Returns the old pointer, to restore it after execution. Not a runtime metadata method, it should be called before the program is executed.
• format_next_item
  Formats a string or a short string / felt252. Returns the formatted string and a boolean indicating whether it’s a string. If can’t format the item, returns None.
