Struct DependencyEntry 

pub struct DependencyEntry {
    pub name: SmolStr,
    pub name_range: TextRange,
    pub constraint_text: Option<(SmolStr, TextRange)>,
    pub constraints: Vec<VersionConstraint>,
    pub range: TextRange,
}

One entry of a dependency field.

Fields

name: SmolStr

The entry’s name as written: a package name, or the literal R.

name_range: TextRange

constraint_text: Option<(SmolStr, TextRange)>

The text between the parentheses, verbatim, and its range — None when the entry carries no parenthesized part at all.

constraints: Vec<VersionConstraint>

The constraints parsed out of constraint_text, in source order. R writes one, but a comma-separated pair ((>= 1.0, < 2.0)) is the reason entry splitting has to be paren-aware, so both are supported.

range: TextRange

The whole entry’s source range.

Implementations

impl DependencyEntry

pub fn malformed_constraint(&self) -> bool

The entry declares a parenthesized part that yielded no constraint — exactly the “unparseable version constraint” case, kept as a fact here and reported as a diagnostic by the consumer.

pub fn lower_bound(&self) -> Option<&VersionConstraint>

The first constraint stating a lower bound, which is what a version floor asks for.

Trait Implementations
