Crate viser 

viser — Video Encoding Optimizer

This is the facade crate for the viser workspace. It does not contain logic of its own; it re-exports each viser library crate as a module so you can depend on a single viser crate instead of a dozen viser-* crates.

Every module is gated behind a feature flag of the same name. All features are enabled by default via the full feature; disable default features and opt in to keep your dependency tree small:

# everything (default)
viser = "0.4"

# only what you need
viser = { version = "0.4", default-features = false, features = ["quality", "hull"] }

The command-line tool lives in the separate viser-cli crate, which installs a viser binary: cargo install viser-cli.
