Struct Manifest 

pub struct Manifest { /* private fields */ }

Create, amend and save a copy of the specified Cargo.toml.

Implementations

impl Manifest

pub fn new(manifest_path: ManifestPath) -> Result<Manifest>

Create new Manifest for the given manifest path.

The path must be to a Cargo.toml.

pub fn with_replaced_lib_to_bin(&mut self) -> Result<&mut Self>

Replaces the [lib] target by a single [bin] target using the same file and name.

pub fn with_added_crate_type(&mut self, crate_type: &str) -> Result<&mut Self>

Add a value to the [lib] crate-types = [] section.

If the value already exists, does nothing.

pub fn profile_optimization_passes(&mut self) -> Option<OptimizationPasses>

Extract optimization-passes from [package.metadata.contract]

pub fn with_profile_release_defaults( &mut self, defaults: Profile, ) -> Result<&mut Self>

Set preferred defaults for the [profile.release] section

Note

Existing user defined settings for this section are preserved. Only if a setting is not defined is the preferred default set.

pub fn with_empty_workspace(&mut self) -> &mut Self

Set [workspace] section to an empty table. When building a contract project any workspace members are not copied to the temporary workspace, so need to be removed.

Additionally, where no workspace is already specified, this can in some cases reduce the size of the contract.

pub fn with_removed_crate_type(&mut self, crate_type: &str) -> Result<&mut Self>

Remove a value from the [lib] crate-types = [] section

If the value does not exist, does nothing.

pub fn with_metadata_package(&mut self) -> Result<&mut Self>

Adds a metadata package to the manifest workspace for generating metadata

pub fn with_dylint(&mut self) -> Result<&mut Self>

pub fn with_merged_workspace_dependencies( &mut self, crate_metadata: &CrateMetadata, ) -> Result<&mut Self>

Merge the workspace dependencies with the crate dependencies.

pub fn rewrite_relative_paths(&mut self) -> Result<()>

Replace relative paths with absolute paths with the working directory.

Enables the use of a temporary amended copy of the manifest.

Rewrites

• [lib]/path
• [dependencies]

pub fn write(&self, manifest_path: &ManifestPath) -> Result<()>

Writes the amended manifest to the given path.
