Standard Library Reference

Cross-target helpers live under std::. Bare calls such as min(a, b) or sha256(data) are rejected (V49) — use the qualified forms.

Authoritative tables also live in cambrian-lang docs/STDLIB.md.

`std::math`

Function	Role
`min`, `max`, `minmax`	Ordering
`abs`, `sign`	Sign
`clamp`	Range clamp
`muldiv`, `muldivmod`	Widening multiply-then-divide
`divmod`, `divc`, `divr`	Division variants
`modpow2`, `pow`	Powers

Function	Role
`parse_u64` / `parse_u8` / `parse_i64` / `parse_uint` / `parse_int`	String → `Option<T>`
`format`	Format string

String ↔ number conversion is never implicit (V50): use parse_* / format.

match std::str::parse_u64(s, 10) {
    some(n) => n,
    none => 0,
}

Function	Role
`sha256`	Hash bytes / string → digest
