Struct OwnedAcr 

pub struct OwnedAcr { /* private fields */ }

Owned variant of Acr.

Inner representation

By default, this type uses a Box<str> internally. The inner representation can be selected at compile time by using one of the following supported values:

• Arc – Use an Arc<str>.
• ThinArc – Use a triomphe::ThinArc<(), u8>. Requires the triomphe cargo feature.
• SmallVec – Use a smallvec::SmallVec<[u8; 32]>. Requires the smallvec cargo feature.

The selected value can be set by using the ruma_identifiers_storage compile-time cfg setting. This setting can be configured using the RUSTFLAGS environment variable at build time, like this:

RUSTFLAGS="--cfg ruma_identifiers_storage=\"{value}\""

Or in .cargo/config.toml:

# General setting for all targets, overridden by per-target `rustflags` setting if set.
[build]
rustflags = ["--cfg", "ruma_identifiers_storage=\"{value}\""]

# Per-target setting.
[target.<triple/cfg>]
rustflags = ["--cfg", "ruma_identifiers_storage=\"{value}\""]

This setting can also be configured using the RUMA_IDENTIFIERS_STORAGE environment variable at compile time, which has the benefit of not requiring to re-compile the whole dependency chain when the value is changed, like this:

RUMA_IDENTIFIERS_STORAGE="{value}"

Implementations

impl OwnedAcr

pub fn zeroize(self)

Available on crate feature events only.

Securely zero memory (aka zeroize) of OwnedAcr.

This method zeroizes this type by writing zeros in its memory location before freeing it. It internally uses the zeroize crate. Note that this type doesn’t implement the zeroize::Zeroize trait because the Zeroize::zeroize method takes a &mut self, which means we could put this type into an inconsistent state if it is used after calling that method. Instead, this method takes ownership of the type, ensuring it’s impossible to misuse it.

Implementation details

If the ruma_identifiers_storage configuration is set to Arc or ThinArc, this type will be zeroized if and only if there is no other strong or weak reference to this same location.
