Struct Manifest 

pub struct Manifest {
    pub manifest_file: ManifestFile,
    pub data: Document,
}

Hold manifest data.

Fields

manifest_file: ManifestFile

Path to Cargo.toml

data: Document

Strict type of Cargo.toml manifest.

Implementations

impl Manifest

pub fn data(&mut self) -> &mut Document

Returns a mutable reference to the TOML document.

If the TOML document has not been loaded yet, this function will load it by calling the load method. If loading fails, this function will panic.

Returns

A mutable reference to the TOML document.

pub fn manifest_file(&self) -> &AbsolutePath

Returns path to Cargo.toml.

pub fn crate_dir(&self) -> CrateDir

Path to directory where Cargo.toml located.

Panics

qqq: doc

pub fn store(&self) -> Result<()>

Store manifest.

Errors

qqq: doc

pub fn package_is(&self) -> bool

Check that the current manifest is the manifest of the package (can also be a virtual workspace).

pub fn local_is(&self) -> bool

Check that module is local. The package is defined as local if the publish field is set to false or the registers are specified.

pub fn resolve_workspace_field( &self, field_name: &str, ) -> Result<String, ManifestError>

Resolves workspace-inherited field value.

When a package uses workspace inheritance (e.g., version.workspace = true), this function locates the workspace root Cargo.toml and extracts the value from [workspace.package] section.

Arguments

• field_name - Name of the field to resolve (e.g., “version”, “edition”, “license”)

Returns

Returns the resolved field value as a string if found.

Errors

Returns error if:

• Cannot locate workspace root manifest
• Cannot read workspace manifest file
• Field not found in workspace.package section
• Field value is not a string

pub fn version(&self) -> Result<String, ManifestError>

Gets package version, handling both direct and workspace-inherited values.

This function properly resolves the version field whether it’s:

• A direct string value: version = "0.2.0"
• Workspace-inherited: version.workspace = true

Returns

Returns the version string if found.

Errors

Returns error if:

• Version field is missing
• Version field has invalid format
• Workspace inheritance is declared but cannot be resolved
