Crate block_sys

👎Deprecated: block-sys is deprecated. Use block2::ffi instead

Raw bindings to Apple’s C language extension of blocks

This crate is deprecated. Use block2::ffi instead.

The documentation for these bindings is a mix from GNUStep’s and Apple’s sources, but the ABI specification is really the place you should be looking!

See also the README.md for more background information, and for how to configure the desired runtime.

Constants

• BLOCK_ALL_COPY_DISPOSE_FLAGSDeprecatedapple
• BLOCK_BYREF_CALLERDeprecated
  The field is an indirect reference to a variable declared with the __block storage qualifier.
• BLOCK_DEALLOCATINGDeprecatedapple
• BLOCK_FIELD_IS_BLOCKDeprecated
  The field is a block. This must be copied by the block copy functions.
• BLOCK_FIELD_IS_BYREFDeprecated
  The field is an indirect reference to a variable declared with the __block storage qualifier.
• BLOCK_FIELD_IS_OBJECTDeprecated
  The value is of some id-like type, and should be copied as an Objective-C object: i.e. by sending -retain or via the GC assign functions in GC mode (not yet supported).
• BLOCK_FIELD_IS_WEAKDeprecated
  The field is an indirect reference to a variable declared with the __block storage qualifier.
• BLOCK_HAS_COPY_DISPOSEDeprecated
  The block descriptor contains copy and dispose helpers. compiler
• BLOCK_HAS_CTORDeprecated
  The helpers have C++ code. compiler: helpers have C++ code
• BLOCK_HAS_EXTENDED_LAYOUTDeprecatedapple

• BLOCK_HAS_SIGNATUREDeprecated
  Block has an Objective-C type encoding. compiler
• BLOCK_INLINE_LAYOUT_STRINGDeprecatedapple

• BLOCK_IS_GLOBALDeprecated
  Block is stored in global memory and does not need to be copied. compiler
• BLOCK_IS_NOESCAPEDeprecatedapple

• BLOCK_NEEDS_FREEDeprecatedapple
  runtime
• BLOCK_REFCOUNT_MASKDeprecated
• BLOCK_SMALL_DESCRIPTORDeprecatedapple
