Cargo Features

[dependencies]
bstr = { version = "1.12.1", default-features = false, features = ["std", "alloc", "unicode", "serde"] }
default = std, unicode

These default features are set whenever bstr is added without default-features = false somewhere in the dependency tree.

std default = alloc

Enables std of memchr and optional serde

memchr:

The 'std' feature permits the memchr crate to use the standard library. This permits this crate to use runtime CPU feature detection to automatically accelerate searching via vector instructions. Without the standard library,
this automatic detection is not possible.

Affects ext_slice::ByteSlice.from_os_str, ext_slice::ByteSlice.from_path, ext_slice::ByteSlice.to_os_str, ext_slice::ByteSlice.to_os_str_lossy, ext_slice::ByteSlice.to_path, ext_slice::ByteSlice.to_path_lossy, ext_vec::ByteVec.from_os_string, ext_vec::ByteVec.from_os_str_lossy, ext_vec::ByteVec.from_path_buf, ext_vec::ByteVec.from_path_lossy, ext_vec::ByteVec.into_os_string, ext_vec::ByteVec.into_os_string_lossy, ext_vec::ByteVec.into_path_buf, ext_vec::ByteVec.into_path_buf_lossy, bstr::io…

alloc std

Enables alloc of memchr and optional serde

memchr:

The 'alloc' feature enables some APIs that require allocation, such as 'Finder::into_owned'. Note that this feature does not enable runtime CPU
feature detection. That still requires 'std'.

Affects ext_slice::ByteSlice.to_str_lossy, ext_slice::ByteSlice.to_str_lossy_into, ext_slice::ByteSlice.repeatn, ext_slice::ByteSlice.replace, ext_slice::ByteSlice.replacen, ext_slice::ByteSlice.replace_into, ext_slice::ByteSlice.replacen_into, ext_slice::ByteSlice.to_ascii_lowercase, ext_slice::ByteSlice.to_ascii_uppercase, ext_vec::ByteVec.unescape_bytes, ext_slice::ByteSlice.to_lowercase, ext_slice::ByteSlice.to_lowercase_into, ext_slice::ByteSlice.to_uppercase, ext_slice::ByteSlice.to_uppercase_into…

unicode default

Enables regex-automata

Affects ext_slice::ByteSlice.fields, ext_slice::ByteSlice.graphemes, ext_slice::ByteSlice.grapheme_indices, ext_slice::ByteSlice.words, ext_slice::ByteSlice.word_indices, ext_slice::ByteSlice.words_with_breaks, ext_slice::ByteSlice.words_with_break_indices, ext_slice::ByteSlice.sentences, ext_slice::ByteSlice.sentence_indices, ext_slice::ByteSlice.trim, ext_slice::ByteSlice.trim_start, ext_slice::ByteSlice.trim_end, ext_slice::ByteSlice.reverse_graphemes, ext_slice::Fields, ext_slice::ByteSlice.to_lowercase, ext_slice::ByteSlice.to_lowercase_into…

serde

Enables serde
