std = ['indexmap?/std']

# Disabling this crate feature allows to drop `hashbrown`, `indexmap` dependencies
# entirely, reducing compilation times and shrink binary sizes.

# A feature that enables validating WebAssembly files. This is enabled by
# default but not required if you're only parsing a file, for example, as
# opposed to validating all of its contents.

#
# This feature is enabled by default. When disabled this crate does not support
# runtime configuration of WebAssembly features. Instead the set of WebAssembly
# features/proposals support are fixed at compile time to `wasmparser`'s default
# set of supported features.
