Enum PineVersion 

pub enum PineVersion {
    V3,
    V4,
    V5,
    V6,
}

The language version a script targets, declared by the //@version=N annotation at the top of a script.

Variants are ordered oldest → newest, so version gates read naturally and stay readable as versions are added:

use pine_core::PineVersion;

let version = PineVersion::V6;
// "namespaced builtins (`ta.sma`) exist from v5 onwards"
assert!(version >= PineVersion::V5);

Default is PineVersion::LATEST.

Implementations

impl PineVersion

pub const LATEST: PineVersion = PineVersion::V6

The newest version this toolchain supports.

pub fn number(self) -> u8

The number as written in //@version=N.

pub fn from_number(n: u8) -> Option<Self>

The version for a //@version=N number, or None if unsupported.

pub fn detect(source: &str) -> Result<Option<Self>, VersionError>

Resolve the version a script targets from its //@version=N annotation.

• Ok(Some(version)) — a supported annotation was found.
• Ok(None) — the script has no annotation. What to assume is the caller’s policy; note that real Pine assumes v1 here.
• Err(VersionError::Unsupported) — the annotation names a version this toolchain cannot compile.
