Function parse_schema 

pub fn parse_schema<I, N, S>(entries: I) -> Result<SpaceSchema>
where
    I: IntoIterator<Item = (N, S)>,
    N: Into<String>,
    S: AsRef<str>,

Parses an ordered sequence of (name, spec) pairs into a SpaceSchema.

This is the entry point the CLI and the TOML overlay call: a TOML table or a --param name=spec list is exactly a sequence of (name, spec-string) pairs. Declaration order is preserved (the schema keeps a Vec plus a name index), and duplicate names are rejected.

use atune_core::space::dsl;

let schema = dsl::parse_schema([
    ("lr", "loguniform(1e-5, 1e-2)"),
    ("batch", "int(16, 512, step=16)"),
    ("amp", "bool"),
])?;
assert_eq!(schema.names().collect::<Vec<_>>(), ["lr", "batch", "amp"]);

Errors

Error::InvalidSpace if any spec fails to parse (prefixed with its parameter name), a name is empty, or a name is declared twice.
