Features

  • demux ... enables libwebpdemux functions.
  • mux ... enables libwebpmux functions.
  • 0_5 ... enables functions introduced in libwebp 0.5.0.
  • 0_6 ... enables functions introduced in libwebp 0.6.0.
  • 1_1 ... enables functions introduced in libwebp 1.1.0.
  • 1_2 ... enables functions introduced in libwebp 1.2.0.
  • static ... statically link against the bundled libwebp.
  • extern-types ... enables #![feature(extern_types)].

Linking

If libwebp is found in the system, it links against the library. Otherwise it builds and links against the bundled libwebp.

In these cases, static link is preferred:

  • For musl target.
  • When cross-compiling.
  • static feature is turned on.
  • LIBWEBP_SYS_STATIC environment variable is set to 1 when building.
