A use tree, that is, the part after the use keyword in a use statement. For example:
use std::collections::HashMap;
use std::collections::*;
use std::collections::HashMap as MyHashMap;
use std::collections::{self, HashMap, HashSet};

Inherited predicates
| fromSource | Holds if this element is from source code. | from Locatable |
| getACfgNode | Gets a control flow node for this AST node, if any. | from AstNode |
| getAPrimaryQlClass | Gets the name of a primary CodeQL class to which this element belongs. | from UseTree |
| getEnclosingBlock | Gets the block that encloses this node, if any. | from AstNode |
| getEnclosingCallable | Gets the immediately enclosing callable of this node, if any. | from AstNode |
| getEnclosingCfgScope | Gets the CFG scope that encloses this node, if any. | from AstNode |
| getFile | Gets the primary file where this element occurs. | from Locatable |
| getLocation | from Locatable | |
| getParentNode | Gets the nearest enclosing parent of this node, which is also an | from AstNode |
| getPath | Gets the path of this use tree, if it exists. | from UseTree |
| getPrimaryQlClasses | Gets a comma-separated list of the names of the primary CodeQL classes to which this element belongs. | from Element |
| getRename | Gets the rename of this use tree, if it exists. | from UseTree |
| getResolveStep | Gets the most immediate element that should substitute this element in the explicit AST, if any. Classes can override this to indicate this node should be in the “hidden” AST, mostly reserved for conversions and syntactic sugar nodes like parentheses. | from Element |
| getUseTreeList | Gets the use tree list of this use tree, if it exists. | from UseTree |
| hasEnclosingCfgScope | Holds if this node is inside a CFG scope. | from AstNode |
| hasPath | Holds if | from UseTree |
| hasRename | Holds if | from UseTree |
| hasUseTreeList | Holds if | from UseTree |
| isFromMacroExpansion | Holds if this node exists only as the result of a macro expansion. | from AstNode |
| isGlob | Holds if this use tree is glob. | from UseTree |
| isInMacroExpansion | Holds if this node is inside a macro expansion. | from AstNode |
| isUnknown | from Element | |
| resolve | Gets the element that should substitute this element in the explicit AST, applying | from Element |
| toString | Gets the string representation of this element. | from Element |
