Crate rattler_index 

Indexing of packages in a output folder to create up to date repodata.json files

Modules

cache

Cache for PackageRecords to optimize retry attempts during concurrent indexing.

error

Defines errors used in this crate.

Structs

ChannelMetadata

Channel metadata written into generated repodata.

IndexChannelConfig

Index options that apply to a single channel.

IndexConfig

Index configuration with default options and per-channel overrides.

IndexFsConfig

Configuration for index_fs

IndexS3Config

Configuration for index_s3

IndexStats

Statistics for the entire indexing operation

RepodataFileMetadata

Metadata for a single repodata file, used to detect concurrent modifications.

RepodataMetadataCollection

Collection of metadata for all critical repodata files that need concurrent access protection.

RepodataRevisionInfo

A revision paired with its metadata: the flattened form of a RepodataRevisions entry, used as indexer input and in reporter messages.

RepodataRevisionMetadata

Metadata for a single RepodataRevisions entry; the revision itself is the map key.

SubdirIndexStats

Statistics for a single subdir indexing operation

Enums

PackageRevisionAssignment

How packages are assigned to repodata revisions while indexing.

PreconditionChecks

Configuration for precondition checks during file operations.

RepodataRevision

A repodata revision.

Functions

ensure_channel_initialized

Ensures that a channel has a valid noarch/repodata.json file.

ensure_channel_initialized_fs

Ensures that a filesystem channel has a valid noarch/repodata.json file.

ensure_channel_initialized_fs_with_channel_metadata

Ensures that a filesystem channel has a valid noarch/repodata.json file and writes channel metadata into the generated file if initialization is needed.

ensure_channel_initialized_s3

Ensures that an S3 channel has a valid noarch/repodata.json file.

ensure_channel_initialized_s3_with_channel_metadata

Ensures that an S3 channel has a valid noarch/repodata.json file and writes channel metadata into the generated file if initialization is needed.

ensure_channel_initialized_with_channel_metadata

Ensures that a channel has a valid noarch/repodata.json file and writes channel metadata into the generated file if initialization is needed.

index

Create a new repodata.json for all packages in the given operator’s root.

index_fs

Create a new repodata.json for all packages in the channel at the given directory.

index_fs_with_channel_metadata

Create a new repodata.json for all packages in the channel at the given directory and write channel metadata into the generated repodata.

index_s3

Create a new repodata.json for all packages in the channel at the given S3 URL.

index_s3_with_channel_metadata

Create a new repodata.json for all packages in the channel at the given S3 URL and write channel metadata into the generated repodata.

index_with_channel_metadata

Create a new repodata.json for all packages in the given operator’s root and write channel metadata into the generated repodata.

package_record_from_archive

Extract the package record from a conda package archive.

package_record_from_conda

Extract the package record from a .conda package file. This function will look for the info/index.json file in the conda package and extract the package record from it.

package_record_from_conda_reader

Extract the package record from a .conda package file content. This function will look for the info/index.json file in the conda package and extract the package record from it.

package_record_from_index_json

Extract the package record from an index.json file.

package_record_from_tar_bz2

Extract the package record from a .tar.bz2 package file. This function will look for the info/index.json file in the conda package and extract the package record from it.

package_record_from_tar_bz2_reader

Extract the package record from a .tar.bz2 package file. This function will look for the info/index.json file in the conda package and extract the package record from it.

write_repodata

Write a repodata.json for all packages in the given configurator’s root. Uses conditional writes based on the provided metadata to prevent concurrent modification issues.

write_retry_policy

Returns a retry policy optimized for write operations with potential lock contention.

Type Aliases

RepodataRevisions

Repodata revisions keyed by revision, mirroring the vN dictionary of the CEP draft https://github.com/conda/ceps/pull/146. Keying encodes uniqueness; insertion order is preserved.
