Struct Pivot 

pub struct Pivot;

Owns the logic for resolving the runtime pivot directory.

Pivot directory

Pivot directory is the current working directory of the runtime process, unless running using Cargo (e.g.: cargo run, cargo test, via IDE, etc.): then it’s the directory containing Cargo.toml.

Implementations

impl Pivot

pub fn resolve() -> PathBuf

Resolves the pivot directory at runtime, which is the directory relative to which the file queries are normally performed.

Example: the config directory, when given as a relative path, is resolved relative to the pivot directory.

When running a binary in a development environment (e.g.: using cargo run, cargo test, or from an IDE), the pivot directory is the directory containing the crate’s Cargo.toml file. This is detected by reading the CARGO_MANIFEST_DIR environment variable at runtime.

When running a binary without using cargo (e.g., by executing the binary in production), the CARGO_MANIFEST_DIR environment variable is normally not set, and the pivot directory is the process’s current working directory.
