Cargo Features

[dependencies]
spi-flash = { version = "0.3.0", default-features = false, features = ["std"] }
default = std

The std feature is set by default whenever spi-flash is added without default-features = false somewhere in the dependency tree.

std default = anyhow, indicatif, jep106, thiserror

Enables std of num_enum ^0.5.7

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

jep106 std

Enables jep106 ^0.2.6

anyhow std
thiserror std

Enables thiserror ^1.0.31

indicatif std
