Struct rustc_middle::dep_graph::DepNodeFilter

source · 
pub struct DepNodeFilter {
    text: String,
}
Expand description

A dep-node filter goes from a user-defined string to a query over nodes. Right now the format is like this:

ⓘ
x & y & z

where the format-string of the dep-node must contain x, y, and z.

Fields§

§text: String

Implementations§

source§

impl DepNodeFilter

source

pub fn new(text: &str) -> DepNodeFilter

source

pub fn accepts_all(&self) -> bool

Returns true if all nodes always pass the filter.
